Our thought is in my opinion […] an appeal in symbols of the self of the present to the self of the immediate future. It is conducted, if not in propositions, in something very much of that nature. I do not think it is, in its movement, propositional; but we are continually drawing up propositions or “judgments” to formulate it. The propositions are an interpretation of the thought, and the thought is partly an interpretation of the percept.
