“It is the essence of certainty to be established only with reservations.”

“Language signifies when instead of copying thought it lets itself be taken apart and put together again by thought. Language bears the sense of thought as a footprint signifies the movement and effort of a body. The empirical use of already established language should be distinguished from its creative use. Empirical language can only be the result of creative language. Speech in the sense of empirical language - that is, the opportune recollection of a preestablished sign – is not speech in respect to an authentic language. It is, as Mallarmé said, the worn coin placed silently in my hand. True speech, on the contrary - speech which signifies, which finally renders "l'absente de tous bouquets" present and frees the sense captive in the thing - is only silence in respect to empirical usage, for it does not go so far as to become a common noun. Language is oblique and autonomous, and if it sometimes signifies a thought or a thing directly, that is only a secondary power derived from its inner life. Like the weaver, the writer works on the wrong side of his material. He has only to do with the language, and it is thus that he suddenly finds himself surrounded by sense.”

“Humanity is not an aggregate of individuals, a community of thinkers, each of whom is guaranteed from the outset to be able to reach agreement with the others because all participate in the same thinking essence. Nor, of course, is it a single Being in which the multiplicity of individuals are dissolved and into which these individuals are destined to be reabsorbed. As a matter of principle, humanity is precarious: each person can only believe what he recognizes to be true internally and, at the same time, nobody thinks or makes up his mind without already being caught up in certain relationships with others, which leads him to opt for a particular set of opinions. Everyone is alone and yet nobody can do without other people, not just because they are useful (which is not in dispute here) but also when it comes to happiness.”

“Being established in my life, buttressed by my thinking nature, fastened down in this transcendental field which was opened for me by my first perception, and in which all absence is merely the obverse of a presence, all silence a modality of the being of sound, I enjoy a sort of ubiquity and theoretical eternity, I feel destined to move in a flow of endless life, neither the beginning nor the end of which I can experience in thought, since it is my living self who think of them, and since thus my life always precedes and survives itself.”

“The world is... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not inhabit only the inner man, or more accurately, there is no inner man, man is in the world, and only in the world does he know himself. ”

“Science manipulates things and gives up living in them. It makes its own limited models of things; operating upon these indices or variables to effect whatever transformations are permitted by their definition, it comes face to face with the real world only at rare intervals. Science is and always will be that admirably active, ingenious, and bold way of thinking whose fundamental bias is to treat everything as though it were an object-in-general - as though it meant nothing to us and yet was predestined for our own use.”

“The perception of other people and the intersubjective world is problematic only for adults. The child lives in a world which he unhesitatingly believes accessible to all around him. He has no awares of himself or of others as private subjectives, nor does he suspect that all of us, himself included, are limited to one certain point of view of the world. That is why he subjects neither his thoughts, in which he believes as they present themselves, to any sort of criticism. He has no knowledge of points of view. For him men are empty heads turned towards one single, self-evident world where everything takes place, even dreams, which are, he thinks, in his room, and even thinking, since it is not distinct from words.”
