The cambridge platonists exemplify the fear that newtonian natural philosophy subverts the status of traditional moral and religious beliefs, Which are strongly supported by the innate idea doctrine since it justifies them independently of the senses and the material universe. Isaac barrow, Friend and teacher of newton, Also employs the doctrine approbatively to support his metaphysics as a science of basic principles that constitute the foundation of natural science. Locke's rejection of the doctrine is analyzed and it is suggested that (...) the platonist's treatment of the active role of the mind in sensation could have been developed in eighteenth century britain if locke's polemic had not been so successful.

Berkeley's theory of signification is explicated and analyzed. Signification: (1) replaces abstract general ideas in the recognition of similar ideas, (2) replaces causation as the relation between ideas of sense and their external sources, (3) replaces substance in the account of sensible objects. Its supposedly simple character cannot be maintained. There are at least three different kinds of signification: signification within categories, Signification across categories, And ontological signification. Berkeley's immaterialistic metaphysics, Relying heavily upon the theory of signification, Is fantastic but (...) fascinating. It is important as a part of a continuous epistemological inquiry of almost two centuries. (shrink)
