Freedom! To fill people's mailboxes, eyes, ears and brains with commercial rubbish against their will, television programs that are impossible to watch with a sense of coherence. Freedom! To force information on people, taking no account of their right not to accept it or their right of peace of mind. Freedom! To spit in the eyes and souls of passersby with advertisements.

A man is happy so long as he chooses to be happy and nothing can stop him.

What a force is laughter.

An engineer cannot participate in irrationality.

Every man always has handy a dozen glib little reasons why he is right not to sacrifice himself.

I had grown up among engineers, and I could remember the engineers of the twenties very well indeed: their open, shining intellects, their free and gentle humor, their agility and breadth of thought, the ease with which they shifted from one engineering field to another, and, for that matter, from technology to social concerns and art. Then, too, they personified good manners and delicacy of taste; well-bred speech that flowed evenly and was free of uncultured words; one of them might play a musical instrument, another dabble in painting; and their faces always bore a spiritual imprint.

And keep as few things as possible, so that you don't have to fear for them. Give them up without a struggle-because otherwise the humiliation will poison your heart. They will take them away from you in a fight, and trying to hold onto your property will only leave you with a bloodied mouth ... But by owning things and trembling about their fate aren't you forfeiting the rare opportunity of observing and understanding?
