“A language is a system of arbitrary vocal symbols by means of which a social group cooperates.”

“The world rarely shrieks its meaning at you. It whispers, in private languages and obscure modalities, in arcane and quixotic imagery, through symbol systems in which every element has multiple meanings determined by juxtaposition.”

“Occasionally in life there are those moments of unutterable fulfillment which cannot be completely explained by those symbols called words. Their meanings can only be articulated by the inaudible language of the heart.”

“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”

“Unlike sharing, where the group is mainly an aggregate of participants, cooperating creates group identity.”

“Philosophy [nature] is written in that great book which ever is 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. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.”
