My only genius talent is inquisitiveness.

My mind is my laboratory.

I have never belonged wholeheartedly to country or State, to my circle of friends or even to my own family... Such isolation is sometimes bitter, but I do not regret being cut off from the understanding and sympathy of other men. I lose something by it,to be sure, but I am compensated for it in being rendered independent of the customs, opinions and prejudices of others, and am not tempted to rest my peace of mind upon such shifting foundations.

Where there is love, there is no imposition.

The dog is very smart. He feels sorry for me because I receive so much mail; that's why he tries to bite the mailman.

The problems that exist in this world can not be solved by the level of thinking that created them.

The ideals which have always shone before me and filled me with the joy of living are goodness, beauty, and truth. To make a goal of comfort or happiness has never appealed to me; a system of ethics built on this basis would be sufficient only for a herd of cattle.
