Comprehensive Notes on Kantian Ethics

Immanuel Kant was born in Königsberg, northeast Germany, on April 22, 1724, as the fourth of nine children.
His parents were devoutly religious, but Kant distanced himself from their strict pietism while maintaining a strong moral sense.
Kant's life was uneventful; he rarely traveled far from his hometown.
He studied classics, physics, and philosophy at the Collegium Fredericianum and the University of Königsberg.
Despite being studious, Kant initially showed no exceptional originality, which surprised his teachers later in life.
After his studies, Kant worked as a private tutor for about a decade, teaching science, mathematics, and philosophy.
He later became a lecturer without an official title, teaching logic and geology, among other subjects.
In 1770, at age 46, Kant was appointed professor of logic and metaphysics.
Kant's lecturing skills, wit, and humor were appreciated by those who knew him well.
He lived a solitary life, never marrying, and followed a highly structured daily routine.
Living during the Age of Enlightenment, Kant witnessed growing confidence in human reason and the rise of Rationalists and Empiricists.
Kant's philosophical contributions were profound, with works like "Critique of Pure Reason" and "The Fundamental Principles of the Metaphysics of Morals."
Kant's moral philosophy focused on the concept of duty.

Kant's transcendental method emphasizes the role of the subject in shaping our experience of the world.
The mind is not a passive recipient but actively structures experience.
The human person, through rational thought, establishes the subjective conditions for objective experience.
The subject plays a fundamental role in determining the nature of reality by "transcending" itself.
Commendable actions stem from adhering to moral laws guided by rationality.

Kant disagreed with both Rationalists and Empiricists.
He affirmed that humans possess a faculty for knowledge independent of experience.
While knowledge begins with experience, not all knowledge arises solely from it.
We have knowledge about causality a priori, derived from rational judgment.
Kant distinguished between analytic and synthetic judgments:
- Analytic judgment: The predicate is contained in the understanding of the subject (e.g., "man is a thinking being").
- Synthetic judgment: The predicate is not contained in the understanding of the subject and requires experience (e.g., "a banana is sweet").
- Synthetic a priori judgment: Contains necessity and universality (a priori) and is not derived from analysis alone (synthetic); for example, $7 + 5 = 12$ .

The mind sets the rules for how we perceive and understand the world.
Human knowledge is limited to the world of experience and is organized by our faculties.
Kant distinguished between:
- Phenomenal reality: The world as we experience it.
- Noumenal reality: The purely intelligible or non-sensual reality.
We can only know reality as it appears to us, not the "thing-in-itself."

A good will aligns with duty, showing fidelity to moral obligations.
Duty involves actions performed out of internal obligation, not external coercion (Deontologism).
Moral actions are determined by motives, with morality being a matter of intent, motive, and will.
Kant distinguished between actions done in accordance with duty and those done from a sense of duty; only the latter carries moral weight.
Duty means acting consistently with moral obligations, even against contrary inclinations.
Humans are autonomous, self-regulating beings capable of making moral decisions.
Autonomy is understood as governing, regulating, and restraining oneself in accordance with universalizable principles.
Respecting an autonomous agent means recognizing their considered value judgment, even if mistaken.

Kant distinguished between two types of duties:
- Perfect duty: Obligations that must always be followed (e.g., not causing harm to others).
- Imperfect duty: Allows for flexibility and is contingent on circumstances (e.g., loving and sharing blessings with others).
Every person has worth and dignity and should be treated as an end in themselves.
Mutual respect for autonomy is the basis of justice.

The will guides our actions according to our understanding of law.
The morality of actions should depend on the will behind them, not the outcomes.
The good will is the sole entity devoid of conditional goodness.
Attributes like health, wealth, and happiness can be used for nefarious purposes and lack intrinsic moral value.
Moral worth depends on the intention behind an action.
Kant contrasted a shopkeeper refraining from overcharging out of self-interest versus out of duty.
Even noble intentions can lead to unforeseen consequences.
True moral worth comes from a rationally guided will that upholds duty and morality.

The categorical imperative embodies true morality and governs human conduct.
It compels individuals to act universally and impartially.
Human reason seeks universal and necessary good, rooted in intention or will.
The categorical imperative is a means to discern moral duty.
Actions are morally commendable when motivated by duty, not consequences or personal gain.

First formulation (universal law formulation): Actions should adhere to maxims that can be universally accepted as laws of nature.
Second formulation (humanity formulation): Treat humanity as an end in itself, never merely as a means to an end.
Third formulation (kingdom of ends formulation): Act in a manner consistent with principles you wish to see universally adopted; respect others' autonomy and dignity.

Kant's framework aimed to establish an absolute moral principle discernable through human reason.
He emphasized duty as universally binding and inherently morally good.
MacIntyre criticized this stance, suggesting it could lead to heartless actions (e.g., Nazis doing their duty without considering consequences).
Kant's framework lacks a method for resolving conflicts between duties.
