The fourth axiom of non-absolutism is the concomitance of the speakable and the unspeakable. A substance is possessed of an infinite number of attributes. It is, however, not possible to express in language those infinite number of attributes taking place every moment. Besides, our span of life and also the range of language have their own limitations. A substance is unspeakable on account of this infinitude of the aspects of a thing.[1] Only one attribute can at best be spoken of in one moment and many in many moments, but never all during any stretch of time. A thing is thus speakable with reference to only a limited number of its attributes.
