Kant & Duty

Kant and Duty

Kant grounded morality not in consequences but in the will to do right. His test, the categorical imperative, asks you to act only on a rule you could will everyone to follow. Lying to escape trouble fails: if all lied when convenient, promises would collapse. A truly moral act is one you could universalize without contradiction.

“Act only according to that maxim whereby you can at the same time will that it should become a universal law.”

Where this sits in the course

“Kant & Duty” is lesson 3 of 3 in Reason Awakens, a course about modern philosophy begins by rebuilding knowledge and duty.. The lessons are sequenced rather than a menu, so this one assumes what came before it.

Reason Awakens is itself one of 18 courses in thinkr. The set opens with what philosophy is, moves through the Stoics and the Eastern traditions, then into what can be known, what exists, how to act and how power works — closing on practical reasoning you can use in an argument this week.

More from Immanuel Kant

“Two things fill the mind with ever new and increasing admiration and awe: the starry heavens above me and the moral law within me.”

“Science is organized knowledge. Wisdom is organized life.”

“Act only according to that maxim by which you can at the same time will that it should become a universal law.”

In the app this lesson is followed by 4 exercises that check whether the idea actually landed — and every answer, right or wrong, is explained rather than scored. That is the part a written page cannot reproduce.
