Plato's Philosophical Reflections on War

so the entire story that leads us to Plato  actually starts in Lydia now to you and me   that would be Turkey but in ancient Greece Lydia  was the place across the Aegean sea where most   of the food came from Lydia was the breadbasket  of Greece a major farming location and a place   that shipped large amounts of food across the  Aegean Sea it was an important economic and   and food-based ally now one of the area's highly  reliant upon Lydia was Athens if you look on the   map you'll see that Athens located of Clare  on the eastern side of the peninsula Greece   would have been one of the major receiving ports  for Lydia's food and grain supplies the problem   happens of course is that when Lydia the major  food supplier is conquered by the Persian Empire   trouble comes to a degree at least for Greece as  part of their food supply is no longer available   the let me try that again the Persians come  in and conquer Lydia and they put in a petty   dictator they call him basically he's a puppet  leader his name is Aristagoras he is appointed   by the Persians mostly because well to put it  indelicately he's a bit of a suck-up he tells   the Persians what they want to see he tells them  exactly that he'll serve faithfully he'll do what   they want him to he'll send them all of the food  and tribute that they need all he needs is to be   put in charge now Aristagoras is actually  working both angles here he wants to become   the actual king of an independent Lydia and if  that means sucking up to the Persians until he   gets the opportunity he's more than willing  to do it so after the Persians head back to   conquer another area Aristagoras waves farewell  faithfully to the Persians and as soon as they're   gone he immediately decides he's going to start  a rebellion he's going to overthrow the Persian   government and he's going to introduce themselves  himself as the hero of Lydia he immediately goes   looking for allies because he knows he needs  allies in order to get rid of the remaining   Persian troops the Persians system that they  have implemented in Lydia even though he is   their puppet dictator he can't just get rid of all  of the things he's agreed to without a little bit   help he immediately goes to what he views as the  strongest military ally he can find that would be oh yeah it's Sparta now there's no leather hot  pants it's not like the movie but Sparta is a   remarkable military power now later on the people  of Athens are going to want to make it sound like   Sparta is a dumb place where you know the Spartans  are just full of dumb jocks that is so not true   Sparta is an area a city-state in Greece which is  actually quite intelligent quite innovative in a   lot of ways for example I mean Sparta actually  has two kings and the two of them often have   different views different political points of  view and the two of them balance each other out   preventing anyone from ever becoming a dangerous  dictator Sparta is completely focused on military   which is why Aristagoras is so interested  in getting Sparta on his side boys go into   military training when they're extremely young  they spend their entire lives until their 30s   living in military barracks focused on military  activities they don't even have homes or a formal   family that they live with until that point of  their lives there are also remarkable warriors   who specialized in combat using a heavy shield and  a spear unlike the movie the Spartans actually use   an extremely strong heavy armor which makes them  less mobile they can't move around in march long   distances in it because the armor is simply too  heavy however on the other hand it means that   they are immobile they're very hard to move when  they line up with that heavy armor and the shields   they are extremely extremely difficult to get  through now Aristagoras shows up in Sparta and   asks for their help in getting rid of the Persians  who have horribly taken over his country and he's   helpless now the Spartans say no we don't know why  the excuse the Spartans give is that they've got   a religious festival going and they can't take  off and go help him in Lydia because they have   to take care of things at home in Sparta now  historically we have no evidence a religious   festival at the time when Aristagoras arrives so  it is possible that the Spartans just see this   whole thing as a bunch of junk and they refuse  to go because they know Aristagoras is playing   them regardless the Spartans turn Aristagoras  down so Aristagoras goes to option number two   option number two would be the Athenians they're  not as powerful military but they are intelligence   and they're easily susceptible to flattery so  Aristagoras goes to Athens he flatters them he   tells them that he knows that they're inspired  by Athena the goddess of strategy he tells them   that they are just so wise and so capable and  he desperately needs their help and shearing off   the Athenians agree to help him they send twenty  ships over to Lydia they take the Lydian capital   and the revolt against the Persians really  starts the Persian government is overthrown   and Lydia is liberated the Athenians then lose  interest they've done what they set out to do   they feel they've done the wise thing they've  liberated the city and they head back home now   the ultimate fallout the reason any of that  matters is that essentially by attacking Lydia   the Athenians have just put themselves on the map  for the Persians the Persians I'm sure we're aware   of them before this but the Persians weren't  really considering them a threat or a power in general you don't want the Persians to notice  you you don't want the Persians to consider you   a threat or anything else the Persian take up a  very large area of the world see map they own the   two major food growing areas Turkey and Egypt they  rule over a massive Empire which is from the few   sources we have and unfortunately we do not have  a lot of sources on Persia from the few sources   we have Persian culture is extremely elegant  extremely advanced it is well-organized with   a lot of bureaucracy around a powerful ruling  family they rule over a variety of different   cultures all subsidiary to the central emperor  of Persia when the Athenians come in and helped   to liberate Lidia they draw the attention of the  Persians the Persians promptly proceeded to come   right back to Lydia and restore control under King  Darius the first and basically the Persians are   interested their curiosity is piqued who exactly  are these Greeks these Athenians who came in and   kicked them out of their newly conquered territory  Persian pride we believe was bruised and they were   interested so the Persians proceeded to launch an  attack on assets now the Persians have a secret   weapon here the Persians have a guy on their  side named Hippias that guy remember Hippias   was the dictator of Athens who got chased to  the top of the Acropolis and Cleomenes and his   revolutionaries threw him out of town and set  up a democracy well Hippias promptly proceeded   to go over to Persia and make friends with the  Persian king as an advisor he's willing to tell   the Persian game everything about Athens about  its defenses about its walls about its military   about its government in exchange for the help  and friendship of the Persian King the Persian   king is pretty darn sure he's got Athens sewn  up they're tiny and he knows everything about   them when he arrives however it turns out  that the Greeks also have a secret weapon   the Greeks the Athenians have a guy on their  site named Miltiades Miltiades actually is a   Persian general who had ticked off the Persian  King Darius and King Darius threatened to kill   Miltiades so Miltiades is left and he went over  to the Athenians and said hey guys I'll tell you   everything about the Persians their strategy  their King their government if you let me help   you guys out and keep me safe so basically both  the Persians and the Athenians have a guy on their   side who knows the other side and they're both  helping out opposing sides now for the Greeks one   of the advantages one of the things Miltiades  tells them is that the Persians are powerful   and unstoppable they consider themselves almost  invincible they land their troops usually by boat   and they simply steamroll they simply go forward  and no one can resist them now the Athenians   specialized in strategy Athena the goddess of  wisdom and strategy is their patron goddess so   the Athenians say okay okay Persians come straight  on Persians are Steamroller we can handle that and   the Athenians come up with a strategy they decide  to meet the Greeks that or the Persians rather at   a particular landing point called Marathon and  they have this plan to take those Persians on the Greeks know that they're extremely  outnumbered now numbers in ancient history   are really questionable because the winners tend  to exaggerate how many numbers they have the the   their enemies have because then when they win  it makes them look more important more epic   contemporary sources sources though estimate that  the Greeks have around eleven thousand soldiers   and the Persians have somewhere between 20,000 and  60,000 so the Greeks are outnumbered at least two   to one possibly six to one the Greeks set up a  force to meet the Persians and when the Persians   come ashore they see Greek forces in front of them  what they don't know is the forces directly in   front of them are actually the worst of the Greek  soldiers the Greeks put their weakest soldiers in   front of the Persians the Persians unload their  troops their weapons their transportation from   the ships and they go forward they do exactly what  Miltiades said they would he's they steamroll they   move directly forward they engage with the Greek  troops and sure enough the Persians are more   powerful in the Greek troops the Greek troops  begin to break and fall back and the Persian   troops move forward now this means technically if  you can picture in your imagination the Persian   forces have now formed a triangle shape a wedge  with a point at the center of the beach moving   inland this is exactly what the Greeks thought was  going to happen this is the plan when the Persians   have engaged with the Greek soldiers and the  Persian soldiers have created this triangle this   wedge heading inward the expert Greek soldiers  come in and they've been hidden on both sides of   the battlefield they sweep in in a pincer movement  attacking the Persians unexpectedly from the sides   when the Persians are already engaged in the  front with the first wave of Greek soldiers   because the Greeks outmaneuver they outwit they  out think the Persians the Persians are defeated   at marathon they were not expecting this kind  of strategy they were expecting to go forward   that Greeks to push back and the Greeks to lose  when the Greeks win and the Persians lose one man   supposedly runs back to the city of Athens to tell  them that the Greeks of one he runs about 21 to 24   miles from Marathon to Athens and he brings the  news and then he dies that messenger is actually   where weak the idea of the modern marathon which  is actually the length of the run from marathon to   the city of Athens only in our marathon you're  not supposed to die then just just saying it's   a little bit different now for the Greeks this is  a huge victory the city of Athens celebrates they   honor Athena they praise Athena for her wisdom  and giving them the strategy they pride themselves   they basically say that they're better than the  Persians they're amazing and the proof for the   people of Athens is the fact that the Persians  are gone this war doesn't continue they withdraw   now the people of Athens are marching around with  a chest puffed out all proud of themselves what   they don't realize is that the Persians have  their own problem the Persian King King Darius   has passed away and there is a complicated fight  over succession over who next it gets to be the   next Persian King the Persians are more concerned  with their own internal struggles and making sure   their government remains stable and strong the  Greeks are kind of an afterthought at this point   it's not that the Greeks are so amazing they  put equip scared away the Persians it's that   the Greeks have not yet become a priority to the  Persians that doesn't happen until 481 when exert   seize launches a punitive expedition to go back  and basically kick the butt of these stupid Punk's   that had caused his dad so many problems now  Xerxes is the new Persian king and he launches   an estimated 150,000 soldiers and about 600 ships  this is terrifying fortunately for the people of   Greece in Athens a young man by the name of  Themistocles has actually been expecting this   now Themistocles actually argues against a plan  that the rest of the Athenian government is in   favor of they've discovered a silver mine outside  of Athens and the government of Athens highly   highly highly suggests that they used this silver  from the silver mine to invest in a huge temple to   Athena because of course she helped them to beat  the Persians and chase the Persians away forever   because Athens is awesome Themistocles says I  don't think so guys they're coming back we need   know that they're gonna be back so Themistocles  leaves actually advocates using the silver to   help the Athenians build a bigger Navy he wins  the debate he wins the argument go democracy   and they actually fund a Navy about 200 ships so  when Xerxes launches this expedition the Athenians   are able to know that they're coming they see  the Persian ships and they warn the rest of the   Greeks now the Greeks are not okay with us they're  terrified Persia is very large and Greece is very   small now we know about this whole fight thanks  to a historian named Herodotus who's actually   incredibly important historian he tells us a lot  of important details about Greek history in fact   he's often referred to as the father of history  because he's one of the first true historians   who's actually trying to record historical  events he's a fantastic storyteller Herodotus   tells wonderful stories I mean everything I told  you guys about mummification with ancient Egypt   all of that is based on Herodotus accounts from  ancient Egypt he tells these great stories I mean   he's the one that tells us about the Persian King  Xerxes when he's angry because a storm blows up in   the Mediterranean Sea Xerxes supposedly orders  his men to beat the waters of the Mediterranean   Sea his punishment for the sea not obeying him  the problem with Herodotus is that the facts are   often questionable because Herodotus is willing  to change the facts in order to make a great story   this is why when we talk for example about how  many troops Xerxes sends against Greece we have   to put a question mark beside it because it's  Herodotus telling us and according to Herodotus   Xerxes and the Persians are horrible barbarians  which we know is not true but Herodotus is kind of   Greek so he's cheering for the Greeks and making  the Persians the baddest of the bad bad guys he's   still a vital source and in some cases he's the  only source we have and he always has a great   story now Herodotus tells us that the Persians  are coming and the Greeks are afraid in fact   according to Herodotus only about thirty one of  several hundred different Greek states agreed to   resist the Persians the rest ready to cave and  just go ahead and give in because the Persians   are terrifying there's a lot of them among those  who will not cave and give in is better called   the Greek league that's Sparta Corinth and Athens  Athens and they agree that Sparta should be the   leader of this league against the Persians because  the Spartans have the greatest amount of military   experience this part of the Greek league decides  there's no way they can beat the Persians straight   out but they can delay and demoralize the Persians  if they can prevent the Persians from effectively   getting inland and resupplying for long enough  for Greek troops to reach the points where they   need to defend against the Persians the delaying  tactic against the Persian landings is given to   the Spartans and the Spartans meet the Persians  at the small narrow pass called Thermopylae so the Spartans set themselves up in a narrow  passageway that we today call Thermopylae now   if you've seen the movie 300 the picture on  the bottom right is actually what Thermopylae   looks like for real which kind of makes the hot  gates from Zack Snyder's film 300 kind of amusing   because it looks nothing like that it's not  nearly so grand and dramatic however it served as   a battleground now those 300 Spartans who led this  stalling action against the Persians were actually   backed by about 3,000 other Greeks but it was  the Spartans who led the attack they're the ones   who stood strong against the Persian attack they  stand for about seven days four of those days of   the Persians wandering around going come on guys  wimp out and leave come on guys wimp out and leave   but the other three days are days of battle and  the fight is dramatic the fight is epic the fight   shows the Spartan determination and their skill  as land troops infantry troops now that Spartan   skill for infantry troops was a vital part of the  war in Greece everywhere not just at Thermopylae   Thermopylae allowed a delaying action that got the  rest of Greece time to be prepared for the overall   invasion however the Persians did come onto the  peninsula of Greece and the blood of Greek troops   led by the Spartans with their expertise in a  land warfare stay in the blood the ground of   Greece it was a bloodbath it was horrifying it  was difficult and it seems like the Greeks are   not going to win against the massive force at  the Persians that is until the Athenians decide   to do something with their Navy now the Athenian  Navy was the best in Greece it was expanded of   course after the Battle of Marathon thanks to  the into the intervention of the Themistocles   Themistocles a manages to convince the people  of Athens to fund about 200 more ships and   those ships are of a very very specific type  and design there's something called triremes triremes are fairly small wooden boats on average  about 120 feet long but they're powered by a   hundred and seventy rowers and three rows now guys  the boat is 120 feet long there's a hundred and   seventy dudes rowing it those 170 guys are laid  out in three different rows of actual rowers for   the ship thus trireme tri means three you can  see in the illustration at the bottom right the   location of those three different rows top middle  and bottom now those 170 rowers are the primary   crew of your vote there are approximately fourteen  spearmen four archers and twenty-five assorted   officers and crew on this boat that number  compared to 170 rowers is a big difference   those hundred and seventy rowers are what these  boats were all about because these boats were   not boats that went out and engaged other ships  fought hand-to-hand boarded other ships instead a   trireme served a very specific purpose if you look  both in the illustration on the bottom right and   on the modern version of the trireme the mock up  that's actually an photograph on your upper left   you will notice that the front of the boat has a  pointed area at the waterline or slightly below   the waterline and you can see it up on the picture  you can see a the ship has little angry eyes and   then in front of it it has something they almost  look like nose and you can see something just   under the water the thing just under the water is  a giant spike the whole point of a trireme is that   you get those hundred and seventy guys running  together you get the boat going incredibly fast   and you Ram other people's boats under the water  you punch holes in them and because you've got a   hundred and seventy guys rowing you can back up  and Ram it again over and over and over again   until you perforate the other person's boat  this was the Athenian specialty the Spartan   specialty was hand-to-hand combat land combat but  the Athenians specialized in naval combat and they   hatched a plan to decimate the Persians forces  their reinforcements and their supply line here's   what happens the Athenian general who actually  came up with the idea for these boats in the first   place Themistocles goes to the king of the Persian  army and says oh great Xerxes king of Persia I   realized now we Greeks are just dumb and weak and  we're never gonna win this battle and because I   know we're gonna wait loose I'm coming to you I  the mystically it's the great Athenian general   I'm coming to you and begging you for mercy please  please please please please let me live I'll tell   you everything about the Greek plans I'll tell you  wherever they're hiding everything I'll tell you   where their boats are I'll tell you everything  you want to know just please let me live now at   this point Themistocles is not actually betraying  the Greeks this is a trap he is pretending to sell   out his people so that he can tell Xerxes where  all of the supposed Greek resupplies are located   he's wanting to make sure that Xerxes believes  him when he tells him where to go to de finally   destroy the Greek army it's not destruction it's  a trap the place Themistocles King Xerxes all   the Greeks final resources are located is in a  small bay called Salamis now Salamis is unique   because it has a long spit of land that covers the  entrance to the bay so you can't see into the bay Salamis doesn't allow any sight lines between a  small island and a spit of land that concealed   the entrance to the bay makes it a wonderful place  for storage because it is protected from the sea   the oceans the storms that come into many other  bays Themistocles swears to King Xerxes that all   of the remaining Greek end forces are hiding at  Salamis and that they've got everything stacked   up all their reinforcements and it'll be an  easy battle and they'll have destroyed the   Greeks ability to continue to fight Xerxes sends  his ships big heavy supply ships loaded down with   reinforcements soldiers food and other cargo to  the Bay of Salamis on the way there they encounter   terrible storms and they lose a number of ships  but they think when they arrive it's all will have   been worth it because they can actually go ahead  and destroy the Greeks now as the Persians come   in the Persian king sends their ships around the  island that's blocking the way into the bay and   they think everything is going well they hear the  sounds of battle they see dead bodies and pieces   of ships and washing out and then someone realizes  those soldiers that are washing out those pieces   of ships those are those are Persian those aren't  Greek something something's wrong and what's wrong   is that the Athenians and their allies have the  triremes and other backup ships waiting just   around the corner and they are perforating the  Persian ships breaking them into pieces and then   they have Spartan troops on land at the end of the  bay so if any of those Persians do manage to swim   to shore the Spartans kill them this battle turns  the tide it destroys the Persian reinforcements   it basically keeps the Persians from being able  to resupply the troops in Greece and gradually   gradually the Persians stranglehold begins  to loosen now even though this is one battle   it's a heck of a battle smaller numbers against  greater numbers it's showy they estimate that   about 40 Greek ships are lost and between two and  three hundred Persian ships are destroyed it's a   definitive victory by strategy by wisdom and the  Athenians claim as theirs they claim that they're   the ones who turn the tide against Persia they  enter an era where the Athenians begin claiming   that they are the best the smartest the most  amazing thinkers and warriors in all Greece during that era the city of Athens is actually run  by a general named Pericles Pericles is both the   military and social leader of Athens he claims  that he is there to lead Athens into a golden   age now in all of his rhetoric about Athens and  its gloriousness Pericles begins changing the   dialogue in an interesting way the whole Salamis  battle that Athenians won Athens won the victory   Athens rules everyone else drools he's actually  an entirely unfair interpretation the Spartans   fight for every inch of land on the peninsula  of Greece the Spartans are actually the ones who   too much of the heavy lifting and holding the  Persians away the Athenians however have they   showey the shiny the flashy Battle of Salamis  where they defeat a larger number but it is not   what actually in the long run grinds down the  Persians to a point where the Battle of Salamis   actually makes a significant difference up to this  point when we read documents from Greece most of   the documents most of the rhetoric the talking is  Greece versus Persia from the Battle of Marathon   from the invasion of Lydia the rhetoric is that  the Greeks are fighting against the Persians the   Greeks are portrayed as the intelligent ones the  Persians are created as the barbarians which is   untrue but it's the way that the rhetoric goes  they're talking smack about their enemies when   Pericles takes over Athens and we enter what  we call the Periclean age all of a sudden that   rhetoric changes that instead of Greece versus  Persia it becomes Athens versus Sparta the   Athenians begin presenting themselves as the  intellectuals as the balanced people whereas   the Spartans are just the dumb jocks now that  is completely unfair and not true Sparta's a   remarkable city it is in some ways as advanced  or more advanced than Athens but the Athenians   certainly do not present it that way they present  Sparta as being hopelessly damaged in fact one of   the things that they repeatedly slam Sparta  for is the fact that Spartan women have more   rights than women anywhere else in Greece and  read it writers from Athens repeatedly state   that Sparta will fall because their women will  eventually destroy the city by having too much   freedom now with this Peroclean age Sparta and  Athens ultimately come to war because each one   of them is trying to lead Greece as a whole each  one is trying to be a city-state that leads the   peninsula forward in a new direction ultimately  Pericles starts a war with Sparta naturally the   Athenians want to keep that war on the water  their specialty is the Navy the Spartans want   to keep that war on the land in the end we don't  know what might have happened because a terrible   plague breaks out in Athens Athens has a lot  of problems with plagues partially because for   all their wisdom and brilliance and intellect  they're often not as practical as they could be   in positioning their drainage fields for sewage  in relation to their freshwater sources it's   terrible outbreak happens and to this day we  do not know exactly what disease it is but it   is terrifying in that disease outbreak the great  general Pericles actually dies leaving the city   of Athens to its own ends but those ends are that  Athens loses Sparta wins this war defeating Athens now for the people of Athens the people who were  so sure that they were the intellectuals they   were the smart ones they ruled Spartans drool  Spartans were dumb jocks Spartans would never   get anywhere Sparta would just be destroyed  Sparta was all about strength and they didn't   acknowledge wisdom and intellect for those people  Sparta winning Athens losing is devastating beyond   words many of the thinkers the intellectuals  in Athens desperately begin looking for answers   questing to try and find out what on earth went  wrong what could have they done better what on   earth happened how did Sparta win in Athens lose  what system of government should have had in place   to do what was seemed so natural to win to show  the gate Greece that they had the right way of   doing things that question raising that question  seeking for those answers is what inspires both   Plato and Aristotle Plato's works and Aristotle's  work Plato's Republic in particular specifically   deals with the question of how do we run  a city the best way possible what is the   right government system in fact what would be the  perfect government system what should we strive   for he is the thinkers of Athens trying to find  out how should they try to run a city what would   be the right way that would prevent something  like this horrible tragedy of Sparta winning and   taking over as the leaders of Greece now that  sets you up for your next quiz which is Plato   and Aristotle now this whole idea of Plato and  Aristotle trying to create a perfect government   let's make it you here next quiz now your next  quiz is it's an easy simple quiz it asks you   to watch a video about Plato and Aristotle and  answer a number of pretty basic questions about   what they think the perfect system would look like  now as you do the quiz remember this entire thing   is about how did Athens lose how did Sparta win  they're looking for an ideal just as they do in   their artwork they're looking for what would the  best possible system be now this whole dead Greek   that guy thing is actually important in relevant  to us because we still look back to those ideas   that Plato and Aristotle float and we look back to  their systems of government even today as we begin   constructing governments as we begin looking  at how to run things and the ideas that they   come up with realistic or not to tap into a very  important parts of human nature so go watch that   little short video answer the questions on that  one and then we will move on now there is another   quiz on Plato and Aristotle and that will get back  to a little bit later on in Greece it's much more   in-depth that deals specifically with Plato's  Republic and what he calls the allegory of the   cave but that's much more philosophy and specific  leadership less about the perfect political system   so we're going to start with the kiddy pool  basic baby quiz first do that one first and   then we'll move on to greed artwork Greek artwork  and then we'll finally move on to Plato's Republic
