"The mental process by which, in any case, the adjustment of acts to ends is effected and which, under its higher forms, becomes the subject-matter of ethical judgments, is, as above implied, divisible into the rise of a feeling or feelings constituting the motive, and the thought or thoughts through which the motive is shaped and finally issues in action. The first of these elements, originally an excitement, becomes a simple sensation; then a compound sensation; then a cluster of partially presentative and partially representative sensations, forming an incipient emotion; then a cluster of exclusively ideal or representative sensations forming an emotion proper; then a cluster of such clusters forming a compound emotion; and eventually becomes a still more involved emotion composed of the ideal forms of such compound emotions. The other element, beginning with that immediate passage of a single stimulus into a single motion, called reflex action, presently comes to be a set of associated discharges of stimuli producing associated motions; constituting instinct. Step by step arise more entangled combinations of stimuli, somewhat variable in their modes of union, leading to complex motions, similarly variable in their adjustments; whence occasional hesitations in the sensori-motor processes. Presently is reached a stage at which the combined clusters of impressions, not all present together, issue in actions not all simultaneous, implying representation of results, or thought. Afterwards follow stages in which various thoughts have time to pass before the composite motives produce the appropriate actions, until at last arise those long deliberations during which the probabilities of various consequences are estimated, and the promptings of the correlative feelings balanced; constituting calm judgment. That, under either of its aspects, the later forms of this mental process are the higher, ethically considered as well as otherwise considered, will be readily seen."[43]
