Combination
Combination
(Lat. combinare, to join) The process of forming a new whole by the union of parts; also the product of such union. Two types of combination are distinguishable
Composition is a union of parts such that the component parts are discernible in the compound. Thus the visual and factual data which combine to form a total percept are recognizable in the resultant percept.
Fusion is a union of parts into a whole in which the identity of the parts is obliterated. Thus the amalgamation of two sense images to form a new quality would, if this phenomenon were psychologically possible, be an instance of psychic fusion.
