German philosopher and one of the central Enlightenment thinkers
Science is organized knowledge. Wisdom is organized life.
All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.
Happiness is not an ideal of reason, but of imagination.
Religion is the recognition of all our duties as divine commands.
Even philosophers will praise war as ennobling mankind, forgetting the Greek who said: 'War is bad in that it begets more evil than it kills.'
Immaturity is the incapacity to use one's intelligence without the guidance of another.
Experience without theory is blind, but theory without experience is mere intellectual play.
It is beyond a doubt that all our knowledge begins with experience.
But although all our knowledge begins with experience, it does not follow that it arises from experience.
To be is to do.
