Hence we may say thj intellection consists in a double process of Separation and Cor bination, Differentiation and Integration, or Analysis and Synthesi! The processes of intellection further involve a property whic is sometimes given as a primary element of intellect, viz., Reteil tiveness, or the power of retaining past impressions, and recallinl! them when no longer supplied by their external cause.

The mere retention of an impression does not|j constitute knowing, or cognition, as the processes of discrimination, etc. constitute it. It is rather the underlying condition of intellective activity! than a part of the knowing process itself. As we shall see presently, it under-1 lies the whole process of intellectual, and indeed of mental development. Constituent Elements of Feeling: Pleasure and Pain. In the case of the feelings or affective states the elementary functions stand out pretty clearly. To be affected by joy, grief, fear, or hope is to be affected agreeably or disagreeably, that is to say, to experience pleasure or its opposite, pain, in a greater or less degree.
