Meet Immanuel Kant: The Categorical Answer
MentorMind

Dare to know
Kant never traveled fifty miles from Königsberg, yet mapped the limits of reason itself. His motto for enlightenment was Sapere aude — dare to use your own understanding — aimed at every age that outsources its thinking to authorities, algorithms, or crowds.
The universal test
His ethics rests on one austere test: could you will your action's rule to be universal law? Lie when convenient — could everyone? Then promises die, and your lie with them. And never treat a person merely as a means: every human is an end. Two sentences that end most rationalizations.
Why they belong at your table
Seat him for the hard ethical call, when convenience whispers. His test takes thirty seconds and spares you years of regret.
