I trust it will be plain that there is nothing fantastic, unreal, or impractical about this way of conceiving people, that is by observing them as facts of the imagination. On the contrary, the fantastic, unreal, and practically pernicious way is the ordinary and traditional one of speculating upon them as shadowy bodies, without any real observation of them as mental facts. It is the man as imagined that we love or hate, imitate, or avoid, that helps or harms us, that moulds our wills and our careers. What is it that makes a person real to us; is it material contact or contact in the imagination? Suppose, for instance, that on suddenly turning a corner I collide with one coming from the opposite direction: I receive a slight bruise, have the breath knocked out of me, exchange conventional apologies, and immediately forget the incident. It takes no intimate hold upon me, means nothing except a slight and temporary disturbance in the animal processes. Now suppose, on the other hand, that I take up Froude’s “Cæsar,” and presently find myself, under the guidance of that skilful writer, imagining a hero whose body long ago turned to clay. He is alive in my thought: there is perhaps some notion of his visible presence, and along with this the awakening of sentiments of audacity, magnanimity and the like, that glow with intense life, consume my energy, make me resolve to be like Cæsar in some respect, and cause me to see right and wrong and other great questions as I conceive he would have seen them. Very possibly he keeps me awake after I go to bed—every boy has lain awake thinking of book people. My whole after life will be considerably affected by this experience, and yet this is a contact that takes place only in the imagination. Even as regards the physical organism it is immeasurably more important, as a rule, than the material collision. A blow in the face, if accidental and so not disturbing to the imagination, affects the nerves, the heart, and the digestion very little, but an injurious word or look may cause sleepless nights, dyspepsia, or palpitation. It is, then, the personal idea, the man in the imagination, the real man of power and fruits, that we need primarily to consider, and he appears to be somewhat different from the rather conventional and material man of traditionary social philosophy. According to this view of the matter society is simply the collective aspect of personal thought. Each man’s imagination, regarded as a mass of personal impressions worked up into a living, growing whole, is a special phase of society; and Mind or Imagination as a whole, that is human thought considered in the largest way as having a growth and organization extending throughout the ages, is the _locus_ of society in the widest possible sense.
