Such Being The Nature Of Mental Life, The Business Of Psychology Is Primarily To Describe In Detail The Various Forms Which Attention Or Conation Assumes Upon The Different Levels Of That Life.

Thus The Same Object May Supply A Practical Perception To One Person And A Speculative One To Another, Or The Same Person May Perceive It Partly Practically And Partly Speculatively.

It Is Convenient To Distinguish The Two Kinds Of Experience Which Have Thus Been Described, The Experienc-ing And The Experienc-ed, By Technical Words.

But Though Cognition Is Not An Element Of Mental Action, Nor Even In Any Real Sense Of The Word An Aspect Of It, The Distinction Of Cognition And Conation Has If Properly Defined A Definite Value.

When We Come To Images Or Memories Or Thoughts, Speculation, While Always Closely Related To Practice, Is More Explicit, And It Is In Fact Not Immediately Obvious That Such Processes Can Be Described In Any Sense As Practical.
