This conception of the mental brings to unity various modes of response jemotional, volitional and intellectual. It is usual to say that there is no fundamental difference among these activities that they are all different phases or aspects of a common action of mind. But Iknow of but one way of making this assertion good: that in which they are seen to be distinctive modes of response to the uncertain. The emotional aspect of responsive behavior is its immediate quality. When we are con- fronted with the precarious, an ebb and flow of emotion marks adisturbance of the even tenor of existence. Emotions are conditioned by the indeterminateness of present situations with respect to their issue. Fear and hope, joy and sorrow, aversion and desire, as perturbations, are qualities of adivided response. They involve concern, solicitude, for what the present situation may become. "Care" signifies two quite different things: fret, worry and anxiety, and cherishing attention to that in whose potentialities we are interested. These two meanings represent different poles of reactive behavior to apresent hav- ing afuture which is ambiguous.
