To invent something, all you need is imagination and a big pile of junk.

During the last century, and part of the one before, it was widely held that there was an unreconcilable conflict between knowledge and belief.

Common sense is nothing more than a deposit of prejudices laid down by the mind before you reach eighteen.

I asked myself childish questions and proceeded to answer them.

Don't listen to their words, fix your attention on their deeds.

Although I cannot believe that the individual survives the death of his body, feeble souls harbor such thought through fear or ridiculous egotism.
