ONT Re: Inquiry Into Information
¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤~~~~~~~~~¤
| In order to understand how these principles of 'à posteriori'
| and inductive inference can be put into practice, we must
| consider by itself the substitution of one symbol for
| another. Symbols are alterable and comparable in
| three ways. In the first place they may denote
| more or fewer possible differing things; in this
| regard they are said to have 'extension'. In the
| second place, they may imply more or less as to
| the quality of these things; in this respect
| they are said to have 'intension'. In the
| third place they may involve more or less
| real knowledge; in this respect they
| have 'information' and 'distinctness'.
| Logical writers generally speak only
| of extension and intension and Kant
| has laid down the law that these
| quantities are inverse in respect
| of each other.
