The essential nature (concerning the soul) cannot be corporeal, yet it — Aristotle

"I do believe for certain, that he [Aristotle] first procured, by the help of the senses, such experiments and observations as he could, to assure him as much as was possible of the conclusion, and that he afterwards sought out the means how to demonstrate it; for this is the usual course in demonstrative sciences. And the reason thereof is, because when the conclusion is true, by the help of the resolutive method, one may hit upon some proposition before demonstrated, or come to some principle known per se; but if the conclusion be false, a man may proceed in infinitum, and never meet with any truth already known."

"[I]ts gravity is the cause; and that which is heavy abides in the middle, and the earth is in the middle: in like manner also, the infinite will abide in itself, through some other cause... and will itself support itself. ...[T]he places of the whole and the part are of the same species; as of the whole earth and a clod, the place is downward; and of the whole of fire, and a spark, the place is upward. So that if the place of the infinite is in itself, there will be the same place also of a part of the infinite."

"The science which has to do with nature clearly concerns itself for the most part with bodies and magnitudes and their properties and movements, but also with the principles of this sort of substance, as many as they may be."

"[A]ll things as subsist from nature appear to contain in themselves a principle of motion and permanency; some according to place, others according to increase and diminuation; and others according to change in quality."

"According to one mode... nature is thus denominated, viz. the first subject matter to every thing which contains in itself the principle of motion and mutation. But after another mode it is denominated form, which subsists according to definition: for as art is called that which subsists according to art, and that which is artificial; so likewise nature is both called that which is according to nature, and that which is natural. ...that which is composed from these is not nature, but consists from nature; as, for instance, man. And this is nature in a greater degree than matter: for every thing is then said to be, when it is form in energy... entelecheia, rather than when it is incapacity."

"[T]he ancient philosophers... all of them assert that the elements, and those things which are called by them principles, are contraries, though they establish them without reason, as if they were compelled to assert this by truth itself. They differ, however... that some of them assume prior, and others posterior principles; and some of them things more known according to reason, but others such as are more known according to sense: for some establish the hot and the cold, others the moist and the dry, others the odd and the even, and others strife and friendship, as the causes of generation. ...in a certain respect they assert the same things, and speak differently from each other. They assert different things... but the same things, so far as they speak analogously. For they assume principles from the same co-ordination; since, of contraries, some contain, and others are contained."

"O dread and silent mount! I gazed upon thee, Till thou, still present to the bodily sense, Didst vanish from my thought: entranced in prayer, I worshipped the Invisible alone."

"Mister Toombs was willing to dissolve the Union to save slavery, Mister Phillips, to save liberty; while Mister Seward, denounced and derided by both, declared that the deepest instinct of the American people was for union. Reserved rights. State rights, limited powers, the advantages of union and disunion, were the cucumbers from which we were busily engaged in distilling light, overlooking the fact of nationality in discussing the conditions of union. We were speculating upon costume. We gravely proved that the clothes were the clothes of a woman, or of a child, without seeing that whatever the clothes might be there was a full-grown man inside of them. "The Constitution is a contract between sovereign States", shouted Mister Toombs, "let Georgia tear it and separate". "The Constitution is a league with hell", calmly replied Mister Phillips, "let New York cut off New Orleans to rot alone". "Oh, dear! it"s a dreadful dilemma", whimpered President Buchanan. "States have no right to secede, and the United States have no right to coerce. Oh, dear me! it"s perfectly awful! I"m the most patriotic of men, but what shall I do? what shall I do?" Separate! Cut off! Secede! It was of a living body they spoke, which, pierced anywhere, quivered everywhere."

"Its never a matter of ethics versus pragmatism; its a question of which informs the other. Humans have shown themselves capable of almost unlimited imagination and innovation—qualities that could be said to define human beings. People have used this capacity to do both great good and great harm. The point is that when humans set their minds to doing something, its frequently possible. It makes sense to first ask what people want to do and why, from an ethical standpoint, and then get to the pragmatic how-to questions. The very process of asking whats right is how people fill out ethics in praxis, to meet new demands and dilemmas, new social conditions and contexts. Anarchism, then, brings an egalitarian ethics out into the world, making it transparent, public, and shared. It maintains an ethical orientation, while continually trying to put such notions into practice, as flawed as the effort might be. When other people come into contact with this ethical compass, they will hopefully "get it" and incorporate the same values into their lives, because it works. It offers directionality to political involvement and buttresses peoples efforts to remake society. It turns surviving into thriving. Thats the crucial difference between a pragmatic versus ethical impulse: people, in cooperative concert, qualitatively transform one anothers lives."

"Thats... the big discovery of this principle of computational equivalence of mine. ...This is something which is kind of a follow-on to Gödels theorem, to Turings work on the ... that there is this fundamental limitation built into science, this idea of computational irreducibility that says that even though you may know the rules by which something operates, that does not mean that you can readily... be smarter that it and jump ahead and figure out what its going to do."

"The art of leading, in operations large or small, is the art of dealing with humanity, of working diligently on behalf of men, of being sympathetic with them, but equally, of insisting that they make a square facing toward their own problems."

"The establishment of "The Times" newspaper is an example, on a large scale, of a manufactory in which the division of labour, both mental and bodily, is admirably illustrated, and in which also the effect of domestic economy is well exemplified. It is scarcely imagined, by the thousands who read that paper in various quarters of the globe, what a scene of organized activity the factory presents during the whole night, or what a quantity of talent and mechanical skill is put in action for their amusement and information."
