School performance, public health, crime rates, clinical depression, tax compliance, philanthropy, race relations, community development, census returns, teen suicide, economic productivity, campaign finance, even simple human happiness - all are demonstrably affected by how (and whether) we connect with our family and friends and neighbours and co-workers.
Nothing can be plainer, than that the motions, changes, decays, and dissolutions, which we hourly see befall natural bodies (and which is what we mean by the course of nature), cannot possibly affect an active, simple, uncompounded substance: such a being therefore is indissoluble by the force of nature, that is to say, the soul of man is naturally immortal.
This commonplace cycle of falling asleep and waking, in darkness, under private cover, with another creature, a pale soft tender mammal, putting faces together in a ritual of affection, briefly settled in the eternal necessities of warmth, comfort, safety, crossing limbs to draw nearer - a simple daily consolation, almost too obvious, easy to forget by daylight.
