Since the narrower or wider community of the peoples of the earth has developed so far that a violation of rights in one place is felt throughout the world, the idea of a cosmopolitan right is not fantastical, high-flown or exaggerated notion. It is a complement to the unwritten code of the civil and international law, necessary for the public rights of mankind in general and thus for the realization of perpetual peace.
Above all do not ask that justice be just: It is just, because it is justice. The idea of a just justice could have originated only in the brain of an anarchist.
Our First Amendment expresses a far different calculus for regulating speech than for regulating nonexpressive conduct and that is as it should be. The right to swing your fist should end at the tip of my nose, but your right to express your ideas should not necessarily end at the lobes of my ears.
I believe we lose immortality because we have not conquered our opposition to death; we keep insisting on the primary, rudimentary idea: that the whole body should be kept alive. We should seek to preserve only the part that has to do with consciousness.
The relativity principle in connection with the basic Maxwellian equations demands that the mass should be a direct measure of the energy contained in a body; light transfers mass. With radium there should be a noticeable diminution of mass. The idea is amusing and enticing; but whether the Almighty is laughing at it and is leading me up the garden path -- that I cannot know.
For the current of our spiritual life creeds, rituals and channels that may thwart or help, according to their fixity or openness. When a symbol or spiritual idea becomes rigidly elaborate in its construction, it supplants the idea which it should support.
The endless cycle of idea and action, / Endless invention, endless experiment, / Brings knowledge of motion, but not of stillness; / Knowledge of speech, but not of silence; / Knowledge of words, and ignorance of The Word.
Liberty is the very last idea that seems to occur to anybody, in considering any political or social proposal. It is only necessary for anybody for any reason to allege any evidence of any evil in any human practice, for people instantly to suggest that the practice should be suppressed by the police.
I do not rush into constructive work. When I get an idea, I start right away to build it up in my mind. I change the structure, I make improvements, I experiment, I run the device in my mind. It is absolutely the same to me whether I operate my turbine in thought or test it actually in my shop. It makes no difference, the results are the same. In this way, you see, I can rapidly develop and perfect an invention, without touching anything.
We should find ourselves committed to killing a great many people whom we now leave living, and to leave living a great many people whom we at present kill. We should have to get rid of all ideas about capital punishment.
All this marked them as vaguely liberal, although their ideas would never congeal into anything like a firm ideology; in this, too, they were American.
The endless cycle of idea and action, / Endless invention, endless experiment, / Brings knowledge of motion, but not of stillness; / Knowledge of speech, but not of silence; / Knowledge of words, and ignorance of The Word.
