ABSTRACT
The problem of concept formation designates the closest point of contact between logic and the philosophy of language; at this point, they seem to merge into an inseparable unity. The totality of linguistic expressions forms, insofar as it is achieved, only an aggregate but not an in itself organized system; the power of organization has exhausted itself in the individual naming and is not adequate to the formation of comprehensive unities. The accidental tenor of associations, which is different from case to case, from individual to individual, can no more explain the ground and origin of the linguistic concepts of cognition than it can the purely logical concepts of cognition. For it is evidently the expression of togetherness immediately presenting itself in the transition from one object to another that constitutes the concept of affinity, so that this concept rests upon certain similarly colored attendant feelings rather than on an actual comparison.
