It would be easy to multiply examples showing the superiority of thought to speech, so far as rapidity is concerned; but those already adduced seem to us sufficient to prove that there is some exaggeration in saying that "man before speaking his thought, thinks his words," if it be understood that all thought is impossible without a word thought. CHAPTER XXIX. ORIGIN AND CHARACTER OF THE RELATION BETWEEN LANGUAGE AND IDEAS. 183. Many ideas seem to be like sensations and sentiments; simple facts, incapable of decomposition, for which reason we cannot explain them with words. Words illustrate ideas; but do they not sometimes also confuse them? When we speak of an idea, we reflect upon it, and I have already remarked[11] that the reflective force of our perceptive ideas is much inferior to their direct force. [11] See Book I., Chs. III. and XXIII. 184. We have sometimes thought that we do, perhaps, know things which we imagine we do not know, and that we are ignorant of things we think we know. It is certain that disputes have been had in all schools of philosophy upon many ideas, without attaining any satisfactory result; and yet these ideas ought to be sufficiently clear to our mind, since we all use them every day without any equivocation. Philosophers have not, as yet, been able to agree upon the ideas of space and time, but the most ignorant men, nevertheless, make use of these words, and whenever the necessity occurs, apply them with exactness. This seems to prove that the difficulty is not in the idea but in its explanation. 185. It has been remarked that there is great truth and exactness in ordinary language, so much so, that the careful observer is astonished at the recondite wisdom hidden in a language; to see how great, how various, and how delicate are the gradations into which the sense of words is distributed. This is not the fruit of reflection; it is the work of reason operating directly, and consequently making use of ideas without reflecting upon them. 186. In ideological investigations some idea of the idea is sought, and it is not noted that if this be necessary to science, another idea of the other idea may be exacted, and that thus an infinite process may be given. It ought to be borne in mind that in treating of simple facts, as well external as internal, no other explanation of them can be demanded than an exposition. 187. _Idea-images_ are a font of error, and probably all ideas explicable by words are not less so. An _idea-image_ induces the belief that there are in our mind no ideas but sensible representations, and the supposition that every idea can be expressed by words, makes us imagine that to be composite which is simple, and attribute to the substance what belongs to the form.
