Overview
This lecture introduces Immanuel Kant’s moral philosophy, focusing on his concept of the categorical imperative and the ethical importance of treating humanity—both others and oneself—as ends in themselves.
Kant's Life and Influence
- Kant maintained a strict daily routine for over 40 years, never leaving his hometown.
- Despite his monotonous lifestyle, Kant became a major Enlightenment thinker, influencing ideas of democracy, animal rights, and international cooperation.
- Kant’s philosophy inspired later thinkers like Albert Einstein and continues to shape moral debates.
Kant’s Moral Philosophy
- Kant believed that moral principles must be universal; if something is wrong, it is always wrong (e.g., lying).
- He developed the idea of categorical imperatives: ethical rules valid for all people, in all situations.
- Rational consciousness (the ability to reason) is, for Kant, the universe’s most valuable resource and should be protected.
The Central Rule: Means and Ends
- Kant’s main rule: "Never treat a human as merely a means to an end, but always as an end in themselves."
- An "end" is something desired for its own sake; a "means" is done to achieve something else.
- Treating people as mere means is unethical; this applies to oneself and others.
Applications and Implications
- Using yourself for mindless pleasure (e.g., procrastination or addiction) is using yourself as a means, thus unethical.
- People-pleasing and seeking approval can lead to treating both yourself and others as means.
- True self-improvement is striving to follow the categorical imperative, making it a moral duty.
- Improving yourself leads to positive effects on others and society (ripple effect).
Character and Self-Mastery
- Developing character means building a life that maximizes your potential and rationality.
- Kant believed most people achieve true character in middle age after overcoming life’s distractions.
- Mastery of oneself is a lifelong duty and the primary moral pursuit.
Key Terms & Definitions
- Categorical Imperative — a universal moral law that applies to everyone, without exceptions.
