The evolution of our spirit is blazed on the dark background of eternity by our individual wakes. Every person can, if he/she wishes, leave a more or less brilliant wake behind them.

If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument... The idea that things must have a beginning is really due to the poverty of our imagination.

The world that I should wish to see would be one freed from the virulence of group hostilities and capable of realizing that happiness for all is to be derived rather from co-operation than from strife. I should wish to see a world in which education aimed at mental freedom rather than imprisoning the minds of the young in rigid armor of dogma calculated to protect them through life against the shafts of impartial evidence.

To realize the unimportance of time is the gate to wisdom.

An individual human existence should be like a river

As men begin to grow civilized, they cease to be satisfied with mere taboos.

Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive and active.
