Graphic Design, which fulfills aesthetic needs, complies with the laws of form and exigencies of two-dimensional space; which speaks in semiotics, sans-serifs, and geometrics; which abstracts, transforms, translates, rotates, dilates, repeats, mirrors, groups, and regroups, is not good design if it is irrelevant.

Semiotics is a general theory of all existing languages... all forms of communication - visual, tactile, and so on... There is general semiotics, which is a philosophical approach to this field, and then there are many specific semiotics.

Semiotics is in principle the discipline studying everything which can be used in order to lie. If something cannot be used to tell a lie, conversely it cannot be used to tell the truth: it cannot in fact be used "to tell" at all.
