A scientist ought to have a healthy disregard for coincidences.

I abominate any organization that denies cats are people!

Of course, if you assume a big enough conspiracy, you can explain anything, including the cosmos itself.

We're free out here, really free for the first time. We're floating, literally. Gravity can't bow our backs or break our arches or tame our ideas. You know, it's only out here that stupid people like us can really think. The weightlessness gets our thoughts and we can sort them. Ideas grow out here like nowhere else - it's the right environment for them. Anyone can get into space, if he wants to hard enough. The ticket is a dream.

Things are different from what I thought. They're much worse.

The dark dangerous forest is still there, my friends. Beyond the space of the astronauts and the astronomers, beyond the dark, tangled regions of Freudian and Jungian psychiatry, beyond the dubious psi-realms of Dr. Rhine, beyond the areas policed by the commissars and priests and motivations-research men, far, far beyond the mad, beat, half-hysterical laughter... the utterly unknown still is and the eerie and ghostly lurk, as much wrapped in mystery as ever.

The right to take a chance, the right to suffer. The right to be unwise, the right to die. These aims are hateful to the government, which values ever frightened mouse and falling sparrow as equal to a tiger burning bright.
