For vacuum rightly conceived of is merely a mathematical quantity extended in the three dimensions, existing per se without heat and cold, soft and hard, rare and dense, and without any natural quality, merely occupying space, as the philosophers maintained before Aristotle, not only within the heavens, but beyond.

Aristotle based his opposition to common ownership not only on logical but also, and principally, on utilitarian grounds. It is impractical because no one takes proper care of objects that are not his: 'How immeasurable greater is the pleasure, when a man feels a thing to be his own, for surely the love of self is a feeling implanted by nature…

Criticism, as it was first instituted by Aristotle, was meant as a standard of judging well; the chiefest part of which is to observe those excellencies which delight a reasonable reader.

The knowledge that is suited to our situation and powers, the whole compass of moral, natural, and mathematical science, was neglected by the new Platonists; whilst they exhausted their strength in the verbal disputes of metaphysics, attempted to explore the secrets of the invisible world, and studied to reconcile Aristotle with Plato, on subjects of which both these philosophers were as ignorant as the rest of mankind.

Slave-owning culture... gives rise to the teleological explanation of the Universe, which reaches its subtlest form in Plato's or Aristotle's philosophies, in which all phenomena are determined by Ideas or Forms. These correspond to the plans formed in the mind of the slave-owner which his slave passively fulfils.

Christopher Caudwell

Aristotle's metaphysics, roughly speaking, may be described as Plato diluted by common sense. He is difficult because Plato and common sense do not mix easily.

Bertrand Russell

There is no such thing as character other than the habitual action, as Mr. Aristotle told us two thousand years ago.

When watching men of power in action it must be always kept in mind that, whether they know it or not, their main purpose is the elimination or neutralization of the independent individual- the independent voter, consumer, worker, owner, thinker- and that every device they employ aims at turning men into a manipulable animated instrument which is Aristotle's definition of a slave.

Aristotle can be regarded as the father of logic. But his logic is too scholastic, full of subtleties, and fundamentally has not been of much value to the human understanding. It is a dialectic and an organon for the art of disputation.

The relationship of point to line bothered the Greeks and led Aristotle to separate the two. Though he admits points are on lines, he says that a line is not made up of points and that the continuous cannot be made up of the discrete. This distinction contributed also to the presumed need for separating number from geometry, since to the Greeks numbers were discrete and geometry dealt with continuous magnitudes.

There is in Aristotle an almost complete absence of what may be called benevolence or philanthropy. The sufferings of mankind... there is no evidence that they cause him unhappiness except when the sufferers happen to be his friends.

Bertrand Russell

Aristotle him selfe sayeth, that medicines be no meate to lyue withall.

Aristotle says that metaphor causes the mind to experience itself in the act of making a mistake.

We can take pride in the fact that there is no science as certain as ours [alchemy] because it teaches by experience which is the mother, the source and the universal cause of all knowledge: and it is for the lack of this that Aristotle and the other philosophers have wondrously failed in their philosophy.

Top-heavy was the ship as a dinnerless student with all Aristotle in his head.

Herman Melville

That Logic has advanced in this sure course, even from the earliest times, is apparent from the fact that, since Aristotle, it has been unable to advance a step, and thus to all appearance has reached its completion.

Secondly, the educated citizen has an obligation to serve the public. He may be a precinct worker or President. He may give his talents at the courthouse, the State house, the White House. He may be a civil servant or a Senator, a candidate or a campaign worker, a winner or a loser. But he must be a participant and not a spectator. "At the Olympic games," Aristotle wrote, "it is not the finest and strongest men who are crowned, but they who enter the lists-for out of these the prize-men are elected. So, too, in life, of the honorable and the good, it is they who act who rightly win the prizes."

John F. Kennedy

Impulse is, after all, the best linguist; its logic, if not conformable to Aristotle, cannot fail to be most convincing.

Henry David Thoreau

I understand the difference between the God and the Lord and I see how great is the difference between the God of Abraham and the God of Aristotle.

Aristotle discovered all the half-truths which were necessary to the creation of science.

Alfred North Whitehead

Although Aristotle may have been right to claim that a desire to know is part of the fundamental constitution of human nature, … Nietzsche is also correct to emphasize that the impulse to evaluate our surroundings, our fellows, and ourselves is at least as deeply rooted in our human nature as is any natural "desire to know." "Der Mensch ist ein abschätzendes Tier."

Aristotle's dictim... may then be formulated somewhat as follows:—Whatever is known of a term may be stated of its equal or equivalent. Or, in other words, Whatever is true of a thing is true of its like.... the value of the formula must be judged by its results;... it not only brings into harmony all the branches of logical doctrine, but... unites them in close analogy to the corresponding parts of mathematical method. All acts of mathematical reasoning may... be considered but as applications of a corresponding axiom of quantity...

William Stanley Jevons

I think there is at least one moral theory of respectable lineage and good independent credentials that can accommodate such fairly minimal intuitions about us and animals. This is the theory Hume offers us. I do not consider Hume a forerunner of utilitarianism, and therefore what I shall go on to say in defense of Hume is not intended as a defense of any version of utilitarianism. I see Hume to be much closer to Aristotle than to Mill, to be offering us a theory about human virtues, not a theory about utility maximization and the duties that might involve.

Somewhere, the deepest desire for us all is to be appreciated, to be loved, to be seen as somebody of value. But not just seen — and Aristotle makes a difference between being admired and being loved. When you admire people, you put them on pedestals. When you love people, you want to be together. So really, the first meeting I had with people with disabilities, what touched me was their cry for relationship.

Aristotle and Heraclitus were both right. A equals A. But A does not equal A.

Aristotle believed that the world did not come into being at some time in the past; it had always existed and it would always exist, unchanged in essence for ever. He placed a high premium on symmetry and believed that the sphere was the most perfect of all shapes. Hence the universe must be spherical.... An important feature of the spherical shape... was the fact that when a sphere rotates it does not cut into empty space where there is no matter and it leaves no empty space behind.... A vacuum was impossible. It could no more exist than an infinite physical quantity.... Circular motion was the most perfect and natural movement of all.

John Rawls says that justice is the 'first virtue' of social institutions, meaning that it is more fundamental than any other, and that we cannot expect individuals to accept social regulation, and engage in social co-operation unless the terms on which society operates are seen as reasonably just. To talk as though Plato and Aristotle saw justice as a matter of the terms of social and political co-operation may suggest a modern and individualist perspective foreign to both. Yet it is not wholly misleading.

When it is known that Plato put his own words in Socrates' mouth (Aristotle says this) there should be no reason to doubt that he could have put his own words into other mouths too.

Robert M. Pirsig

In its application to natural science Grosseteste based his method of verification and falsification on two assumptions about the nature of reality. (a) The first was the principle of the uniformity of nature, meaning that forms are always uniform in their operations.... In support of this principle he quoted 'Aristotles II de Generat.:...'the same cause, provided it remains in the same condition, cannot produce anything but the same effect.' (b) The second assumption Grosseteste made was that of the principle of economy, or lex parsimoniae. This he also derived from Aristotle, who stated it as a pragmatic principle.

Alistair Cameron Crombie

What happened was, 2,400 years ago, the Greek Gang of Three, by whom I mean Aristotle, Plato and Socrates, started to think based on analysis, judgment and knowledge. At the same time, church people, who ran the schools and universities, wanted logic to prove the heretics wrong. As a result, design and perceptual thinking was never developed. People assumed philosophers were doing it and so they blocked anyone else from doing it. But philosophers were not. Philosophers may look out at the world from a stained-glass window, but after a while they stop looking at the world and start looking at the stained glass.
