Note 304 — Chapter XVI

Some of the supporters of the interjectional theory in this extreme, not to say extravagant form, appear to go on the assumption that primitive and hitherto speechless man already differed from the lower animals in presenting conceptual thought. This assumption would, of course, explain why man alone began to invest his instinctive cries, &c., with the character of names. But, from a psychological point of view, any such assumption is obviously a putting of the cart before the horse. I make this remark in order to add that the objection would not apply if the ideation were supposed to be pre-conceptual—i.e. beyond the level reached by any brute, though not yet distinctively human. Later on, I myself espouse a theory to this effect.
