12. THINKING AND APPREHENSION.
Says Jevons: “Simple apprehension is the act of the mind by which we merely become aware of something,or have an idea or impression of it brought into the mind;” while Hyslop states that “The process of knowledge which gives us percepts is apprehension.” It is obvious that the idea of the latter is that apprehension yields individual notions only, while Jevons, in citing the term iron as an illustration of his definition, would infer that the general notion is the product of apprehension. The term is strikingly ambiguous and will not be referred to often in this treatise. If the student desires a definition this will cover the concensus of opinion on the meaning of apprehension. Apprehension is that process of the knowing mind which yields the percept and concept. Some logicians give to the thinking mind the three aspects of apprehension, judging and reasoning.
