A sign is a representation of an object that implies a connection between itself and its object. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence. (This is in contrast to a symbol which stands for another thing, as a flag may be a symbol of a nation).
The way a sign signifies is called semiosis which is a topic of semiotics and philosophy of language.
How a sign is perceived depends upon what is intended or expressed in the semiotic relationship of:
- Signification
- Significance (i.e. meaning)
- Importance
Thus, for example, people may speak of the significance of events, the signification of characters, the meaning of sentences, or the import of a communication. Different ways of relating signs to their objects are called modes of signification.
Uses of conventional signs are varied. Usually the goal is to elicit a response or simply inform. That can be achieved by marking something, displaying a message (i.e. a notice), drawing attention or presenting evidence of an underlying cause (for instance, medical symptoms signify a disease), performing a bodily gesture, etc.
Famous quotes containing the word sign:
“It is always a sign of an unproductive time when it concerns itself with petty and technical aspects [in philology], and likewise it is a sign of an unproductive person to pursue such trifles.”
—Johann Wolfgang Von Goethe (1749–1832)
“It is a sign of contraction of the mind when it is content, or of weariness. A spirited mind never stops within itself; it is always aspiring and going beyond its strength.”
—Michel de Montaigne (1533–1592)
“It is at the same time by poetry and through poetry, by and through music, that the soul glimpses the splendors found behind the tomb; and when an exquisite poem brings tears to one’s eyes, these tears are not the sign of excessive pleasure, they are rather witness to an irritated melancholy, to a condition of nerves, to a nature exiled to imperfection and which would like to seize immediately, on this very earth, a revealed paradise.”
—Charles Baudelaire (1821–1867)
