إن الفلسفة تبدأ عندما يبدأ الإنسان يتعلم الشك، وخصوصاً الشك في المعتقدات التي يحبها، والعقائد والبديهيات أو الحقائق المقررة التي يؤمن بها ويقدسها.

في اللامبالاة، فلسفة إنها صفة من صفات الأمل

Filosofia se trădează pe sine atunci când degenerează în dogmatism, adică într-o ştiinţă fixată în formule, definitivă, completă. A face filozofie înseamnă a fi pe drum; în filozofie întrebările sunt mult mai importante decât răspunsurile, şi fiecare răspuns devine o nouă întrebare

كل علم يصير شعرا بعد ان كان فلسفة

Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.

Philosophy, though unable to tell us with certainty what is the true answer to the doubts which it raises, is able to suggest many possiblities which enlarge our thoughts and free them from the tyranny of custom. Thus, while diminishing our feeling of certainty as to what things are, it greatly increases our knowledge as to what the may be; it removes the somewhat arrogant dogmatism of those who have never travelled into the region of liberating doubt, and it keeps alive our sense of wonder by showing familar things in an unfamilar aspect

To be a philosopher is not merely to have subtle thoughts, nor even to found a school, but so to love wisdom as to live according to its dictates, a life of simplicity, independence, magnanimity and trust.

Philosophy is written in this all-encompassing book that is constantly open to our eyes, that is the universe; but it cannot be understood unless one first learns to understand the language and knows the characters in which it is written. It is written in mathematical language, and its characters are triangles, circles, and other geometrical figures; without these it is humanly impossible to understand a word of it, and one wanders in a dark labyrinth.

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.

When a philosopher says something that is true then it is trivial. When he says something that is not trivial then it is false.

Listen to the discussion between any two philosophers one of whom upholds determinism, and the other liberty: it is always the determinist who seems to be in the right. He may be a beginner and his adversary a seasoned philosopher. He can plead his cause nonchalantly, while the other sweats blood for his. It will always be said of him that he is simple, clear and right. He is easily and naturally so, having only to collect thought ready to hand and phrases ready-made: science, language, common sense, the whole of intelligence is at his disposal. Criticism of an intuitive philosophy is so easy and so certain to be well received that it will always tempt the beginner. Regret may come later, — unless, of course, there is a native lack of comprehension and, out of spite, personal resentment toward everything that is not reducible to the letter, toward all that is properly spirit. That can happen, for philosophy too has its Scribes and its Pharisees.

Philosophy, for Plato, is a kind of vision, the 'vision of truth' ... Everyone who has done any kind of creative work has experienced, in a greater or less degree, the state of mind in which, after long labour, truth or beauty appears, or seems to appear, in a sudden glory – it may only be about some small matter, or it may be about the universe ... I think most of the best creative work, in art, in science, in literature, and in philosophy, has been the result of such a moment.

Philosophy is an art form — art of thought or thought as art

قد لا أعتقد بجميع القصص و الأساطير التي جاءت بالكتب الدينية ولكن لا يمكن أن أعتقد بعدم وجود عقل مدبر لهذا العالم. إن القليل من الفلسفة ينزع بعقل الإنسان إلى الإلحاد ولكن التعمق فيها ينتهي بعقول الناس إلى الإيمان لأن عقل الإنسان عندما ينظر إلى الأسباب الثانوية المبعثرة قد يتوقف عندها ولا يتجاوزها، ولكن عندما يشاهد تسلسلها و اتحادها، و اتصالها بعضها بعضا ينتهي به ذلك إلى الإيمان بوجود العناية الإلهية.
