In the kingdom of ends everything has either a price or a dignity. Whatever has a price can be replaced by something else as its equivalent; on the other hand, whatever is above all price, and therefore admits of no equivalent, has a dignity. But that which constitutes the condition under which alone something can be an end in itself does not have mere relative worth, i.e., price, but an intrinsic worth, i.e., a dignity.

If education is to develop human nature so that it may attain the object of its being, it must involve the exercise of judgment.

Nature does nothing in vain, and in the use of means to her goals she is not prodigal.

We are not rich by what we possess but by what we can do without.

Beauty presents an indeterminate concept of Understanding, the sublime an indeterminate concept of Reason.

If justice perishes, human life on Earth has lost its meaning.
