TAILIEUCHUNG - The Principles of Psychology

To the reader who is tired of so much Erkenntnisstheorie I can only say that I am so myself, but that it is indispensable, in the actual state of opinions about Sensation, to try to clear up just what the word means. Locke's pupils seek to do the impossible with sensations, and against them we must once again insist that sensations 'clustered together' cannot build up our more intellectual states of mind | THE PRINCIPLES OF PSYCHOLOGY 1 The Principles of Psychology By William James Get any book for free on: Get any book for free on: THE PRINCIPLES OF PSYCHOLOGY 2 CHAPTER XVII. SENSATION. After inner perception, outer perception! The next three chapters will treat of the processes by which we cognize all times the present world of space and the material things which it contains. And first, of the process called Sensation. SENSATION AND PERCEPTION DISTINGUISHED. The words Sensation and Perception do not carry very definitely discriminated meanings in popular speech, and in psychology also their meanings run into each other. Both of them name processes in which we cognize an objective world; both (under normal conditions) need the stimulation of incoming nerves ere they can occur; Perception always involves Sensation as a portion of itself; and Sensation in turn never takes place in adult life without Perception also being there. They are therefore names for different cognitive functions, not for different sorts of mental fact. The nearer the object cognized comes to being a simple quality like 'hot,' 'cold,' 'red,' 'noise,' 'pain,' aprehended irrelatively to other things, the more the state mind approaches pure sensation. The fuller of relations an object is, on the contrary; the more it is something eased, located, measured, compared, assigned to a function, etc., etc.; the more unreservedly do we call the state mind a perception, and the relatively smaller is the part it which sensation plays. Sensation, then, so long as we take the analytic point of [p. 2] view, differs from Perception only in the extreme simplicity of its object or content. [1] Its function is that of mere acquaintance with a fact. Perception's function, on the other hand, is knowledge about [2] a fact; and this knowledge admits of numberless degrees of complication. But in both sensation and perception we perceive the fact as an immediately present outboard reality, and
