FEELING ALWAYS PRESENT IN MENTAL CONTENT.--No phase of our mental life is without the feeling element. We look at the rainbow with its beautiful and harmonious blending of colors, and a feeling of pleasure accompanies the sensation; then we turn and gaze at the glaring sun, and a disagreeable feeling is the result. A strong feeling of pleasantness accompanies the experience of the voluptuous warmth of a cozy bed on a cold morning, but the plunge between the icy sheets on the preceding evening was accompanied by the opposite feeling. The touch of a hand may occasion a thrill of ecstatic pleasure, or it may be accompanied by a feeling equally disagreeable. And so on through the whole range of sensation; we not only _know_ the various objects about us through sensation and perception, but we also _feel_ while we know. Cognition, or the knowing processes, gives us our "whats"; and feeling, or the affective processes, gives us our "hows." What is yonder object? A bouquet. How does it affect you? Pleasurably. If, instead of the simpler sensory processes which we have just considered, we take the more complex processes, such as memory, imagination, and thinking, the case is no different. Who has not reveled in the pleasure accompanying the memories of past joys? On the other hand, who is free from all unpleasant memories--from regrets, from pangs of remorse? Who has not dreamed away an hour in pleasant anticipation of some desired object, or spent a miserable hour in dreading some calamity which imagination pictured to him? Feeling also accompanies our thought processes. Everyone has experienced the feeling of the pleasure of intellectual victory over some difficult problem which had baffled the reason, or over some doubtful case in which our judgment proved correct. And likewise none has escaped the feeling of unpleasantness which accompanies intellectual defeat. Whatever the contents of our mental stream, "we find in them, everywhere present, a certain color of passing estimate, an immediate sense that they are worth something to us at any given moment, or that they then have an interest to us."
