The common consciousness is not only the source from which the individual gets his mode of speech, thought and action, but the court of appeal which decides what is fact. If a question is raised whether the result of a scientific experiment is what it is alleged by the original maker of the experiment to be, the appeal is to the common consciousness: any one who chooses to make the experiment in the way described will find the result to be of the kind alleged; if everyone else, on experiment, finds it to be so, it is established as a fact of common consciousness; if no one else finds it to be so, the alleged discovery is not a fact but an erroneous inference. Now, it is not merely with regard to external facts or facts apprehended through the senses, that the common consciousness is accepted as the court of appeal. The allegation may be that an emotion, of a specified kind--alarm or fear, wonder or awe--is, in specified circumstances, experienced as a fact of the common consciousness. Or a body of men may have a common purpose, or a common idea, as well as an emotion of, say, common alarm. If the purpose, idea or emotion, be common to them and experienced by all of them, it is a fact of their common consciousness. In this case, as in the case of any alleged but disputed discovery in science, the common consciousness is the court of appeal which decides the facts, and determines whether what an individual thinks he has discovered in his consciousness is really a fact of the common consciousness. The idea of powers superior to man, the emotion of awe or reverence, which goes with the idea, and the purpose of communicating with the power in question are facts, not peculiar to this or that individual consciousness, but facts of the common consciousness of all mankind. The child up to a certain age has no consciousness of self: the absence of self-consciousness is one of the charms of children. The child imitates its elders, who speak of him and to him by his name. He speaks of himself in the third person and not in the first person singular, and designates himself by his proper name and not by means of the personal pronoun 'I'; eventually the child acquires the use and to some extent learns the meaning of the first personal pronoun; that is, if the language of the community to which he belongs has developed so far as to have produced such a pronoun. For there was a period in the evolution of speech when, as yet, a first personal pronoun had not been evolved; and that, probably, for the simple reason that the idea which it denotes was as unknown to the community as it is to the child whose absence of self-consciousness is so pleasing. For a period, the length of which may have been millions of years, the common consciousness, the consciousness of the community, did not discover or discriminate, in language or in thought, the existence of the individual self.
