“An empty stomach is not a good political adviser.”

“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.”

“Politics is for the moment and equation is 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 only justifiable purpose of political institutions is to ensure the unhindered development of the individual.”

“Yes, we have to divide up our time like that, between our politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever. ”

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