 In Implication and Linear Inference, for example, Bosanquet defends his long-standing view that inference is “every process by which knowledge extends itself” (op. cit., p. 2). It is made possible by implication—i.e., the property of each system whereby one can go from one part to all other parts. Standard formal logic (e.g., linear inference or syllogistic) is only a limited form of inference for, as Bosanquet reminded his readers, logical principles are not part of some abstract real but are the expression of the movement and life of the mind.
