Consciousness... does not appear to itself chopped up in bits. Such words as 'chain' or 'train' do not describe it fitly as it presents itself in the first instance. It is nothing jointed; it flows. A 'river' or a 'stream' are the metaphors by which it is most naturally described. In talking of it hereafter, let us call it the stream of thought, of consciousness, or of subjective life. Source of the expression 'stream of consciousness'.
William JamesThe total possible consciousness may be split into parts which co-exist but mutually ignore each other.
William JamesThe exercise of voluntary attention in the schoolroom must therefore be counted one of the most important points of training that take place there; and the first-rate teacher, by the keenness of the remoter interests which he is able to awaken, will provide abundant opportunities for its occurrence.
