| No study seems so trivial as that of formal logic, not only at first
| but until after long research.  It is far too indeterminate to be of
| much use in actual reasoning, and it is too simple to interest like
| Mathematics by involutions and resolutions of forms.  It has, however,
| a deep significance, one which was perceived most clearly by Aristotle
| and Kant and the recognition of which gave their two philosophies such
| pre-eminent vitality.  It is the circumstance that the commonest and most
| indispensible conceptions are nothing but objectifications of logical forms.
| The categories of Kant are derived from the logical analysis of judgments,
| and those of Aristotle (framed before the accurate separation of syntax
| and logic) are derived from a half-logical half-grammatical analysis
| of propositions.  Now upon the table of the categories philosophy is
| erected, -- not merely metaphysic but the philosophy of religion,
| of morals, of law, and of every science.  To form a table of the
| categories is, therefore, the great end of logic.
