Still it seems to be a fact that any very powerful feeling, reaching to the full intensity of which our consciousness is normally capable, is commonly diminished by a contemporaneous stroke of cognitive effort: hence it is a general difficulty in the way of exact observation of our emotions that the object cognised seems to shrink and dwindle in proportion as the cognitive regard grows keen and eager. How then are we to reconcile this with the proposition first laid down, that pleasure only exists as we are conscious of it? The answer seems to be that the mere consciousness of a present feeling--apart from any distinct representative elements--cannot diminish the feeling of which it is an indispensable and inseparable condition: but in introspective cognition we go beyond the present feeling, comparing and classifying it with remembered or imagined feelings; and the effort of representing and comparing these other feelings tends to decrease the mere presentative consciousness of the actual pleasure. I conclude, then, that there is a real danger of diminishing pleasure by the attempt to observe and estimate it. But the danger seems only to arise in the case of very intense pleasures, and only if the attempt is made at the moment of actual enjoyment; and since the most delightful periods of life have frequently recurring intervals of nearly neutral feeling, in which the pleasures immediately past may be compared and estimated without any such detriment, I do not regard the objection founded on this danger as particularly important.
