The death of dogma is the birth of morality.

But a lie is a lie, and in itself intrinsically evil, whether it be told with good or bad intents.

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.

How then is perfection to be sought? Wherein lies our hope? In education, and in nothing else.

I assert that, in any particular natural science, one encounters genuine scientific substance only to the extent that mathematics is present.

A science of all these possible kinds of space [the higher dimensional ones] would undoubtedly be the highest enterprise which a finite understanding could undertake in the field of geometry... If it is possible that there could be regions with other dimensions, it is very likely that God has somewhere brought them into being.

Nothing is divine but what is agreeable to reason.
