use the symbol has acquired a nature,
| which may be described thus, that when it is brought before
| the mind certain principles of its use -- whether reflected on
| or not -- by association immediately regulate the action of the
| mind;  and these may be regarded as laws of the symbol itself
| which it cannot 'as a symbol' transgress.
