| The last lecture was devoted to the fundamental inquiry
| of the whole course, that of the grounds of inference.
|
| We first distingushed three kinds of reference
| which every true symbol has to its object.
|
| In the first place, every true symbol is applicable to some real thing.
| Hence, every symbol whether true or not asserts itself to be applicable to
| some real thing.  This is the 'denotation' of the symbol.  All that we know
| of things is as denotative
