An attempt to lay the foundations for the psychological study of the lexical component of language, in which an attempt is made to make the link between the perceptual and the linguistic aspects of 'sense'. Thus, the book contains investigations of the sensory field and the organizational principles of the perceptual world; a fragment of a conceptual theory based on the concept of routines, intended to deal with language; an attempt to put together these insights into the principles of perception and conceptual theory; and an analysis of various parts of the lexicon of English from this perspective (including color, kinship, spatial temporal, and causal relations, the meaning patterns of verbs of motion, possession, and vision, the language of communication).
