A Quote by Isaac Newton

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.
Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena.
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.
Philosophy's position with regard to science, which at one time could be designated with the name "theory of knowledge," has been undermined by the movement of philosophical thought itself. Philosophy was dislodged from this position by philosophy.
Logical investigations can obviously be a useful tool for philosophy. They must, however, be informed by a sensitivity to the philosophical significance of the formalism and by a generous admixture of common sense, as well as a thorough understanding both of the basic concepts and of the technical details of the formal material used. It should not be supposed that the formalism can grind out philosophical results in a manner beyond the capacity of ordinary philosophical reasoning. There is no mathematical substitute for philosophy.
Philosophy - reduced, as we have seen, to philosophical discourse - develops from this point on in a different atmosphere and environment from that of ancient philosophy. In modern university philosophy, philosophy is obviously no longer a way of life, or a form of life - unless it be the form of life of a professor of philosophy.
Conservatism is the antidote to tyranny. It's the only one. It's based on thousands of years of human experience. There is nothing narrow about the conservative philosophy. It's a liberating philosophy. It is a magnificent philosophy. It is a philosophy for the ages, for all times.
Philosophy aims at the logical clarification of thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations. Philosophy does not result in 'philosophical propositions', but rather in the clarification of propositions. Without philosophy thoughts are, as it were, cloudy and indistinct: its task is to make them clear and to give them sharp boundaries.
When we read with attention the poetical and philosophical monuments of the East--above all, those of India, which are beginning to spread in Europe--we discover there many a truth, and truths so profound, and which make such a contrast with the meanness of the results at which European genius has sometimes stopped, that we are constrained to bend the knee before the philosophy of the East, and to see in this cradle of the human race the native land of the highest philosophy.
Environmental philosophy just is philosophy full stop. It only sprung up as distinct subfield because mainstream philosophy was ignoring some of the most important philosophical challenges of our time.
One of the things I want to do in the book is to explore how philosophy can be done in literature. I start doing that in the first chapter, by introducing the idea of "philosophy by showing". What literature/philosophy shows is how to look at some important facets of life in a new way, thus changing the frame in which subsequent philosophical argument proceeds.
When one begins to reflect on philosophy—then philosophy seems to us to be everything, like God, and love. It is a mystical, highly potent, penetrating idea—which ceaselessly drives us inward in all directions. The decision to do philosophy—to seek philosophy is the act of self-liberation—the thrust toward ourselves.
In elaborating how "philosophy by showing" works, and in defending the idea that literature and music can contribute to philosophical "showing", I am also doing something more standardly philosophical. But I view most of the book as an interweaving of philosophy and literary criticism. If that entails a broadening of a standard idea of philosophy, it's a broadening I'd like to see happen.
At one point I took a copy of Berkeley's Principles from my father's library. That was the first philosophy book I read. I found it fascinating and wanted to read more philosophy.
In philosophy, when we make use of false principles, we depart the farther from the knowledge of truth and wisdom exactly in proportion to the care with which we cultivate them, and apply ourselves to the deduction of diverse consequences from them, thinking that we are philosophizing well, while we are only departing the farther from the truth; from which it must be inferred that they who have learned the least of all that has been hitherto distinguished by the name of philosophy are the most fitted for the apprehension of truth.
Self-taught poverty is a help toward philosophy, for the things which philosophy attempts to teach by reasoning, poverty forces us to practice.
Olympism is a philosophy which, by blending sport with culture, seeks to create a way of life based on the joy found in effort, the educational value of good example and respect for universal ethical principles.
