A Sign is always less than the thing it points to, and a symbol is always more than we can understand at first sight. Therefore we stop at the sign but go on to the goal it indicates... but we remain with the symbol because it promises more than it reveals.
A Sign is made up of two closely linked elements. The first is the signified, which is the mental or cognitive image we have in our heads of the thing or object being referred to.
The Sign is that by means of which man frees himself from the here and now for abstraction.

A Sign is that which points to something and also points to itself as something that points to something. The sign is always double.

The Sign represents something for somebody while the signifier is something that represents a subject for another signifier.
