Simone Weil said this quote

At the very best, a mind enclosed in language is in prison. It is limited to the number of relations which words can make simultaneously present to it; and remains in ignorance of thoughts which involve the combination of a greater number. These thoughts are outside language, they are unformulable, although they are perfectly rigorous and clear and although every one of the relations they involve is capable of precise expression in words. So the mind moves in a closed space of partial truth, which may be larger or smaller, without ever being able so much as to glance at what is outside.
