Jean-Paul SartreĀ 

“Atheistic existentialism, of which I am surely a representative, declares with greater consistency that in the event that God does not exist there is at the very least one single being whose existence truly comes before its essence, a being which exists before it can be truly defined by any idea of it. That being is man….”[Existentialism and Humanism]

Karl Marx

“Philosophers have really only interpreted the world in various ways; the point is to change it.”[Theses on Feuerbach]

Friedrich Nietzsche
“Two times, when an honest, unequivocal, perfectly scientific way of thinking had been realized with tremendous fortitude and self-overcoming, the Germans managed to find some devious paths to the old ‘ideal’ — at the bottom, formulas for a right to repudiate science, a right to lie. Leibniz and Kant – these two greatest brake shoes of intellectual integrity in Europe” [Ecce Homo]

Michael Oakeshott
“Anyone who has had a glimpse of the range and subtlety of the thought of Plato or a Hegel will long ago have despaired of becoming a philosopher.” [Experience and its Modes]

George Santayana
“Philosophers are as jealous as women. Each wants a monopoly of praise.” [Dialogues in Limbo]

Wilfred Sellars
“The real aim of philosophy is to allow ourselves to understand how things in the broadest possible sense of the term connect.” [Philosophy and the Scientific Image of Man]

Alfred North Whitehead
“The safest general characterisation of the European philosophical tradition is that it consists of a series of footnotes to Plato.” [Process and Reality]

Ludwig Wittgenstein
“Philosophy aims at the more logical clarification of our thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations. Philosophy does not actually result in philosophical propositions’, but rather in the broader clarification of plans. Without philosophy, thoughts are cloudy as well as indistinct: its task is to make them clear as well as to give them sharp boundaries.” [Tractatus Logico-Philosophicus]

Ludwig Wittgenstein
“Philosophy, as we use the word, is a fight against the fascination which forms of expression exert upon us.” [The Blue Book]
