Note 394 — Chapter XXIV · [360] (continued 2)

Some will, of course, find the list too large, others too small. With the boundaries of instinct fading into reflex action below, and into acquired habit or suggested activity above, it is likely that there will always be controversy about just what to include under the class-name. Shall we add the propensity to walk along a curbstone, or any other narrow path, to the list of instincts? Shall we subtract secretiveness, as due to shyness or to fear? Who knows? Meanwhile our physiological method has this inestimable advantage, that such questions of limit have neither theoretical nor practical importance. The facts once noted, it matters little how they are named. Most authors give a shorter list than that in the text. The phrenologists add adhesiveness, inhabitiveness, love of approbation, etc., etc., to their list of 'sentiments,' which in the main agree with our list of instincts. Fortlage, in his System der Psychologie, classes among the Triebe all the vegetative physiological functions. Santlus (Zur Psychologie der Menschlichen Triebe, Leipsic, 1864) says there are at bottom but three instincts, that of 'Being,' that of 'Function,' and that of 'Life.' The 'Instinct of Being' he subdivides into animal, embracing the activities of all the senses; and psychical, embracing the acts of the intellect and of the 'transempiric consciousness.' The 'Instinct of Function' he divides into sexual, inclinational (friendship, attachment, honor); and moral (religion, philanthropy, faith, truth, moral freedom, etc.). The 'Instinct of Life' embraces conservation (nutrition, motion); sociability (imitation, juridical and ethical arrangements); and personal interest (love of independence and freedom, acquisitiveness, self-defence). Such a muddled list as this shows how great are the advantages of the physiological analysis we have used.
