“Politics is for the moment and equation is for eternity.”

“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.”

“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. ”

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

“Concern for man himself and his fate must always constitute the chief objective of all technological endeavors...in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.”

“The only justifiable purpose of political institutions is to ensure the unhindered development of the individual.”
