When the time comes in which one could, the time has passed in which one can.

In this world, all power rests upon force.

Without imagination, there is no goodness, no wisdom.

Not what we experience, but how we perceive what we experience, determines our fate.

Even virtue is an art; and even its devotees are divided into those who practise it and those who are merely amateurs.

Authors from whom others steal should not complain, but rejoice. Where there is no game there are no poachers.

Kindness which is not inexhaustible does not deserve the name.
