The word “Symbol” will in this book be used as the common name for that class of Signs which represent, to those that can interpret them, the objects they do quite regardless of any resemblances to them (although such may have influenced the original choice of the signs), and equally so of any actual connexions therewith, (however close such connexions there may be,) but solely because those interpreters have habits of mind, whether inherited or acquired, that lead them whenever they perceive the signs straightway to think of those Objects.
