The power of expressing thought in words, of compressing experiences into spoken and written symbols, of being eloquent or convincing either by tongue or pen, is thus a high function of intelligence. The able speaker and writer has always been powerful, and he has always found a high social value in promulgating the ideas of those too busy or unfitted for this task, and he has been the chief agent in the unification of groups. The danger that lies in words as the symbols of thought lies in the fact pointed out by Francis Bacon[1] (and in our day by Wundt and Jung) that words have been coined by the mass of people and have come to mean very definitely the relations between things as conceived by the ignorant majority, so that when the philosopher or scientist seeks to use them, he finds himself hampered by the false beliefs inherent in the word and by the lack of precision in the current use of words. Moreover, words are also a means of stirring up emotions, hate, love, passion, and become weapons in a struggle for power and therefore obscure intelligence. [1] This is Bacon's "Idols of the Market Place." Words, themselves, arise in our social relations, for the solitary human would never speak, and the thought we think of as peculiarly our own is intensely social. Indeed, as Cooley pointed out, our thought is usually in a dialogue form with an auditor who listens and whose applause we desire and whose arguments we meet. In children, who think aloud, this trend is obvious, for they say, "you, I, no, yes, I mustn't, you mustn't," and terms of dialogue and social intercourse appear constantly. Thought and words offer us the basis of definite internal conflict: one part of us says to the other, "You must not do that," and the other answers, "What shall I do?" Desire may run along smoothly without distinct, internal verbal thought until it runs into inhibition which becomes at once distinctly verbal in its, "No! You musn't!" But desire obstructed also becomes verbal and we hear within us, "I will!" We live secure in the belief that our thoughts are our own and cannot be "read" by others. Yet in our intercourse we seek to read the thoughts of others--the real thoughts--recognizing that just as we do not express ourselves either accurately or honestly, so may the other be limited or disingenuous. Whenever there occurs a feeling of inferiority, the face is averted so the thoughts may not be read, and it is very common for people mentally diseased to believe that their thoughts are being read and published. Indeed, the connection between thoughts and the personality may be severed and the patient mistakes as an outside voice his own thoughts.
