Politics is a pendulum whose swings between anarchy and tyranny are fueled by perpetually rejuvenated illusions.

Politics is for the present, but an equation is for eternity.

All of us who are concerned for peace and triumph of reason and justice must be keenly aware how small an influence reason and honest good will exert upon events in the political field.

Equations are more important to me, because politics is for the present, but an equation is something for eternity.

One must divide one's time between politics and equations. But our equations are much more important to me, because politics is for the present, while our equations are for eternity.

The Revolution introduced me to art, and in turn, art introduced me to the Revolution!
