As a supplement to the law of resultants, and yet at the same time in a certain sense as an expression for the same psychical regularity, we have "the law of conditioning relations." Just as the law of resultants joins into one unified expression the forms of psychical synthesis, so we may say that the law of relations is the analytic principle, which arranges under one general rule the relations of the components of one such synthetic whole. This rule consists in the fact that the psychical elements of a product stand in internal relations to each other, out of which the product itself necessarily arises, while at the same time the character of a new creation (a character that belongs to all psychical resultants) is caused by these relations. By inner relations we mean such as depend upon the qualitative constitution of the separate contents, and in so far stand, as a specifically different and at the same time complementary condition, in contradistinction to those external relations, which are determined by their formal arrangement. In this sense this distinction between external and internal relations corresponds to the difference in the ways of viewing the phenomena by the natural sciences and psychology respectively. The processes of nature are absolutely determined by the connection of temporal and spatial relations, in which the elements of the phenomena stand to each other. The mental processes on the other hand cannot, because of their subjection to natural phenomena, dispense with these external relations, but their inmost nature rests on the internal qualitative relations of the elements bound into one whole.
