The trouble with the younger generation is that they don't stay young for very long.

God always takes the simplest way.

Do you remember how electrical currents and 'unseen waves' were laughed at? The knowledge about man is still in its infancy.

Persistence is the most powerful force on earth, it can move mountains.

Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.

[O]nly if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective.

I want to know all Gods thoughts; all the rest are just details.
