IT has already been pointed out that every mental process presents three phases for discussion, cognitive, affective and conative. Up to the present we have examined them together in the processes under discussion, giving to each a more or less equal value, but in the more complicated grades of mental development, which take place during the life of the individual, it is more convenient to examine the organization of what we may call affective or emotional processes, cognitive or thought processes, and conative processes or sentiments. Nevertheless, we must remember that these terms are only conveniences, and that there can be no real separation of the three phases.
