There is a realm of Social Objectivity, a realm of organization, activity, purpose and power, not physical in character, not mechanical in nature, which is set in opposition to individual will, purpose, power, and activity. How is the individual related to this objective social world? Three main types of theory have sought to answer this question. On the one hand, there is a type of theory, doubtless the oldest type, a type which arises easily in a period when social changes are slow, which sees in the objective social world something really separate and distinct from individual life, having a non-human origin, and deriving its power from something other than the human will. On the other hand, there is an extreme individualism, which emphasizes individual separateness, which posits as a _datum_ the individuality which we have seen to be a social product, and thinks of the objective social realm as a mere mechanical, mathematical summing up of individual factors, or as a something which individuals have consciously made, by contract or agreement, or what not. Finally, there is a type of theory, to which the present writer would adhere, which finds a false antithesis in the contrast thus sharply made between society and individual, which holds that the individual is not, in his psychological activity, so much set off from the activities of his fellows as the contrast would indicate, but rather shares in the give and take of a larger mental life. This larger mental life is completely accounted for when all the individuals are completely accounted for, but it cannot be accounted for by considering the individuals _separately_. No individual is completely, or primarily, accounted for until his _relations_ to the rest of the group are analyzed. Thinkers who start out with the individuals separately conceived, and then seek to combine them in some arithmetical way, abstract from those organic social relations which constitute the very heart of the phenomenon we are seeking to explain. The parts are in the whole, but the whole is not the _sum_ of the parts. The relationships are not arithmetical, additive, mechanical, but are vital and organic. Men's minds _function_ together, in an organic unity.[25]
