In dark days, your best shelter is your clever thoughts!

A little spoon for a cup of soup teaches to be patient; and the big one, to be greedy!

Failure knocks the door of the unprepared minds very often.

Angels want peace; devils want war! Wise man wants tranquillity and creation; stupid man wants noise and destruction!

The 'stream' we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.

All the donkeys I knew had small ears!
