Note AQ — PREFACE

This confusion between conceiving a concrete thing and knowing the meaning of abstract terms is as old as Toland’s Christianity not Mysterious, and, indeed, has its germ, though not its development, in the teaching of his assumed master, Locke. Locke taught that all our knowledge is founded on simple ideas, and that a complex idea is merely an accumulation of simple ones. Hence Toland maintained that no object could be mysterious or inconceivable if the terms in which its several attributes are expressed have ideas corresponding to them. But, in point of fact, no simple idea can be conceived as an object by itself, though the word by which it is signified has a perfectly intelligible meaning. I cannot, e.g., conceive whiteness by itself, though I can conceive a white wall, i.e., whiteness in combination with other attributes in a concrete object. To conceive attributes as coexisting, however, we must conceive them as coexisting in a certain manner; for an object of conception is not a mere heap of ideas, but an organized whole, whose constituent ideas exist in a particular combination with and relation to each other. To conceive, therefore, we must not only be able to apprehend each idea separately in the abstract, but also the manner in which they may possibly exist in combination with each other.
