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

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

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.

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.

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

Eventually, Aristotle appeared among the Greeks. He improved the methods of logic and systematized its problems and details. He assigned to logic its proper place as the first philosophical discipline and the introduction to philosophy. Therefore he is called the First Teacher.

Aristotle would... by no means admit that mathematics was divorced from aesthetic; he could conceive, he said, of nothing more beautiful than the objects of mathematics.

Thomas Little Heath

For Aristotelian physics the membership of an object in a given class was of critical importance, because for Aristotle the class defined the essence or essential nature of the object, and thus determined its behavior in both positive and negative respects.

Such knowledge [of contemporary physicists] is clearly not the same as that derived by abstraction from individual cases: abstraction can provide us with knowledge of accidents but not necessary attributes as such. If we find that the search for essences can in fact only take the form of abstraction from individual cases then Aristotle's account of what counts as an explanation in physics is an unrealisable ideal.

Stephen Gaukroger

The word ontology comes from the Greek ontos for being and logos for word. It is a relatively new term in the long history of philosophy, introduced by the 19th century German philosophers to distinguish the study of being as such from the study of various kinds of beings in the natural sciences. The traditional term for the types of beings is Aristotle's word category, which he used for classifying anything that can be said or predicated about anything.

Coleridge observes that all men are born Aristotelians or Platonists. The latter feel that classes, orders, and genres are realities; the former, that they are generalizations. For the latter, language is nothing but an approximative set of symbols; for the former, it is the map of the universe. The Platonist knows that the universe is somehow a cosmos, an order; that order, for the Aristotelian, can be an error or a fiction of our partial knowledge. Across the latitudes and the epochs, the two immortal antagonists change their name and language: one is Parmenides, Plato, Spinoza, Kant, Francis Bradley; the other, Heraclitus, Aristotle, Locke, Hume, William James.

Jorge Luis Borges

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.

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.

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

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."

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.

Thus, from admiration of one wise and innocent child, and from a misheard remark, the process that not even Aristotle could codify was triggered. Where do you get your ideas? I purposely mishear things.

But why had science lost its way in the first place? What appeal could these teachings of Pythagoras and Plato have had for their contemporaries? They provided, I believe, an intellectually respectable justification for a corrupt social order. The mercantile tradition that had led to Ionian science also led to a slave economy. You could get richer if you owned a lot of slaves. Athens in the time of Plato and Aristotle had a vast slave population. All that brave Athenian talk about democracy applied only to a privileged few.

When I saw that Moses' version of the Genesis of the world did not fit sufficiently in many ways with Aristotle and the rest of the philosophers, I began to have doubts about the truth of all philosophers and started to investigate the secrets of nature.

Gerardus Mercator

The Encyclopedia presents a contemporary version of the ancient encyclopedic ideal of Aristotle, the Scholastics, Leibniz, the Encyclopedists, and Comte.

Charles W. Morris

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

Alfred North Whitehead

It is by no means certain that we advance our philosophical quest by reading Plato or Aristotle. It may increase our knowledge of history but not of the world.

Jostein Gaarder

The dominant concept in Aristotle's philosophy of nature is his notion of causation.... The final cause states that each substance has an inherent purpose. Thus there must be a purpose or design in the acorn such that it always grows into an oak tree. This aspect of existence is indicated by the word entelechy; this means the purpose that guides things to develop in one way rather than another.

What is philosophy? This is a notoriously difficult question. One of the easiest ways of answering it is to say that philosophy is what philosophers do, and then point to the writings of Plato, Aristotle, Descartes, Hume, Kant, Russell, Wittgenstein, Sartre, and other famous philosophers. However, this answer is unlikely to be of much use to you if you are just beginning the subject, as you probably won't have read anything by these writers.

Nigel Warburton

Aristotle was guided by that which appears to be the nature of things. The Ashariyah refused to ascribe to God ignorance about anything... they preferred to admit the above-mentioned absurdities. The Mu'tazilites refused to assume that God does what is wrong and unjust; on the other hand, they would not contradict common sense and say that it was not wrong to inflict pain on the guiltless, or that the mission of the Prophets and the giving of the Law had no intelligible reason. They likewise preferred to admit the above-named absurdities. But they even contradicted themselves, because they believe on the one hand that God knows everything, and on the other that man has free will. By a little consideration we discover the contradiction.

In aesthetic discourse, no interpretative-critical analysis, doctrine or programme is superseded, is erased, by any later construction. The Copernican theory did correct and supersede that of Ptolemy. The chemistry of Lavoisier makes untenable the early phlogiston theory. Aristotle on mimesis and pathos is not superseded by Lessing or Bergson. The Surrealist manifestos of Breton do not cancel out Pope's Essay on Criticism though they may well be antithetical to it.

Kuhn's revolution was not yet a Kuhnian revolution, although he dated his intention to write the book that became Structure to the time of his wrestle with Aristotle. What he needed was a historical exemplar. He found it in the Copernican revolution.

John L. Heilbron

The sense of tragedy - according to Aristotle - comes, ironically enough, not from the protagonist's weak points but from his good qualities. Do you know what I'm getting at? People are drawn deeper into tragedy not by their defects but by their virtues.... [But] we accept irony through a device called metaphor. And through that we grow and become deeper human beings.

Haruki Murakami

Aristotle himself says, that medicines be no meat to live withal.

Yet Aristotle's excellence of substance, so far from being associated with the grand style, is associated with something that at times comes perilously near jargon.
