“Psychology is a more tricky field, in which even outstanding authorities have been known to run in circles, 'describing things which everyone knows in language which no one understands.”

From Italian: La filosofia è scritta in questo grandissimo libro, che continuamente ci sta aperto innanzi agli occhi (io dico l'Universo), ma non si può intendere, se prima non il sapere a intender la lingua, e conoscer i caratteri ne quali è scritto. Egli è scritto in lingua matematica, e i caratteri son triangoli, cerchi ed altre figure geometriche, senza i quali mezzi è impossibile intenderne umanamente parola; senza questi è un aggirarsi vanamente per un oscuro labirinto.
Other translations:
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. This book is written in the 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.
The Assayer (1623), as translated by Thomas Salusbury (1661), p. 178, as quoted in The Metaphysical Foundations of Modern Science (2003) by Edwin Arthur Burtt, p. 75.
Philosophy is written in this grand book — I mean the universe — which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth.

Context: The famous Rgveda text, "One is the Truth, the sages speak of it differently" (1.64.46), is often employed to explain away doctrinal differences as merely semantic ones. The point of this text, as its context makes quite clear, is not really to dismiss the significance of the different ways in which we speak of the One or to see these ways as equally valid. The text is really a comment on the limited nature of human language. Such language must by nature be diverse in its attempts to describe that which is One and finally indescribable. The text, however, is widely cited in ways that seem to make interreligious dialogue redundant.
