Thomas Paine Quotes

To derive two or three general Principles of Motion from Phænomena, and afterwards to tell us how the Properties and Actions of all corporeal Things follow from those manifest Principles, would be a very great step in Philosophy.

This incomparable Author having at length been prevailed upon to appear in public, has in this Treatise given a most notable instance of the extent of the powers of the Mind; and has at once shown what are the Principles of Natural Philosophy, and so far derived from them their consequences, that he seems to have exhausted his Argument, and left little to be done by those that shall succeed him.a

The evil that has resulted from the error of the schools, in teaching natural philosophy as an accomplishment only, has been that of generating in the pupils a species of atheism. Instead of looking through the works of creation to the Creator himself, they stop short, and employ the knowledge they acquire to create doubts of his existence. They labour with studied ingenuity to ascribe every thing they behold to innate properties of matter, and jump over all the rest by saying, that matter is eternal.

The mere man of pleasure is miserable in old age, and the mere drudge in business is but little better, whereas, natural philosophy, mathematical and mechanical science, are a continual source of tranquil pleasure, and in spite of the gloomy dogmas of priests and of superstition, the study of these things is the true theology; it teaches man to know and admire the Creator, for the principles of science are in the creation, and are unchangeable and of divine origin.

Whoso turns his attention to the bitter strifes of these days and seeks a reason for the troubles that vex public and private life must come to the conclusion that a fruitful cause of the evils which now afflict, as well as of those which threaten us, lies in this: that false conclusions concerning divine and human things, which originated in the schools of philosophy, have crept into all the orders of the state, and have been accepted by the common consent of the masses.

There is no more open door by which you can enter into the study of natural philosophy than by considering the physical phenomena of a candle

As in Mathematicks, so in Natural Philosophy, the Investigation of difficult Things by the Method of Analysis, ought ever to precede the Method of Composition. This Analysis consists in making Experiments and Observations, and in drawing general Conclusions from them by Induction, and admitting of no Objections against the Conclusions, but such as are taken from Experiments, or other certain Truths. For Hypotheses are not to be regarded in experimental Philosophy.

The severe schools shall never laugh me out of the philosophy of Hermes, that this visible world is but a picture of the invisible, wherein as in a portrait, things are not truly, but in equivocal shapes, and as they counterfeit some real substance in that invisible fabric.

Philosophy is written in that great book which ever lies before our eyes — I mean the universe — but we cannot understand it if we do not first learn the language and grasp the symbols, in which it is written.

Our present work sets forth mathematical principles of philosophy. For the basic problem of philosophy seems to be to discover the forces of nature from the phenomena of motions and then to demonstrate the other phenomena from these forces. It is to these ends that the general propositions in books 1 and 2 are directed, while in book 3 our explanation of the system of the world illustrates these propositions.

I am myself an empiric in natural philosophy, suffering my faith to go no further than my facts. I am pleased, however, to see the efforts of hypothetical speculation, because by the collisions of different hypotheses, truth may be elicited and science advanced in the end.

Geology, perhaps more than any other department of natural philosophy, is a science of contemplation. It requires no experience or complicated apparatus, no minute processes upon the unknown processes of matter. It demands only an enquiring mind and senses alive to the facts almost everywhere presented in nature. And as it may be acquired without much difficulty, so it may be improved without much painful exertion.

All the sciences have a relation, greater or less, to human nature; and...however wide any of them may seem to run from it, they still return back by one passage or another. Even Mathematics, Natural Philosophy, and Natural Religion, are in some measure dependent on the science of MAN; since they lie under the cognizance of men, and are judged of by their powers and faculties.

I will simply express my strong belief, that that point of self-education which consists in teaching the mind to resist its desires and inclinations, until they are proved to be right, is the most important of all, not only in things of natural philosophy, but in every department of dally life.

Physics is unable to stand on its own feet, but needs a metaphysics on which to support itself, whatever fine airs it may assume towards the latter.

In Philosophy, the contemplations of man do either penetrate unto God, or are circumferred to Nature, or are reflected and reverted upon himself. Out of which several inquiries there do arise three knowledges, Divine Philosophy, Natural Philosophy, and Human Philosophy or Humanity. For all things are marked and stamped with this triple character of the power of God, the difference of Nature and the use of Man.

This you may say of man - when theories change and crash, when schools, philosophies, when narrow dark alleys of thought, national, religious, economic, grow and disintegrate, man reaches, stumbles forward, painfully, mistakenly sometimes. Having stepped forward, he may slip back, but only half a step, never the full step back.

We must reason in natural philosophy not from what we hope, or even expect, but from what we perceive.

In every philosophical school, three thinkers succeed one another in the following way: the first produces out of himself the sapand seed, the second draws it out into threads and spins a synthetic web, and the third waits in this web for the sacrificial victims that are caught in it--and tries to live off philosophy.

I have presented principles of philosophy that are not, however, philosophical but strictly mathematical-that is, those on which the study of philosophy can be based. These principles are the laws and conditions of motions and of forces, which especially relate to philosophy.

Philosophy treats of physics where a more careful knowledge is required because the problems which come under this head are numerous... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.

If you're studying Geology, which is all facts, as soon as you get out of school you forget it all, but Philosophy you remember just enough to screw you up for the rest of your life.

In many ways, the effort to study philosophy was my rebellion away from medicine. I'm the son of two Indian immigrant physicians, so the natural path for me would have been to become a doctor. I ended up doing the master's degree at Oxford in politics, philosophy, and economics while already having a seat in medical school. I was keeping that as my escape hatch. But my hope was that I might become a philosopher or something else entirely.

If God did not exist, he would have to be invented.

Today the West is awakening to its wants; and the "true self of man and spirit" is the watchword of the advanced school of Western theologians. The student of Sanskrit philosophy knows where the wind is blowing from, but it matters not whence the power comes so longs as it brings new life.
