Immanuel Kant Quotes

Immanuel Kant

All our knowledge begins with the senses,

proceeds then to the understanding,
and ends with reason.

There is nothing higher than reason.

All the interests of my reason,

speculative as well as practical,

combine in the three following questions:

1. What can I know?
2. What ought I to do?
3. What may I hope?

But although all our knowledge begins with experience,

it does not follow that it arises from experience.

Experience without theory is blind,

but theory without experience is mere intellectual play.

He who is cruel to animals becomes
hard also in his dealings with men.

We can judge the heart of
a man by his treatment of animals.

Immaturity is the incapacity to use
one's intelligence without the guidance of another.

Science is organized knowledge.
Wisdom is organized life.

Thoughts without content are empty,
intuitions without concepts are blind.
