Senescence, the Last Half of Life
Hall, G. Stanley (Granville Stanley)
Geriatrics
poor victim perhaps longs for but is unable to command the means of
attaining, feeling himself useless and a grievous burden, a just living
mummy, torpid, neither really sleeping nor waking; and in the end with
every natural function sinking synchronously but so gradually that
observers could not be sure whether each slow breath or heart beat was
really the last or just when the Great Divide had really been crossed
where Sleep embraces its brother, Death. Something like this would be
the fate of the soma, after it had been abandoned by the germ plasm,
if a really natural death occurred, that is, if, by some of the many
disharmonies that pervade the body, some organ or part did not break
down before the others were worn out and drag them to its own doom,
which is what always really occurs in fact.
If we look at the matter from the more psychological and Lamarckian
viewpoint, suggested, for example, by the thesis of Hering, that memory
is the most fundamental trait of organized matter, a view elaborated by
Simon’s theory of mnemes and engrams, all experience is more or less
permanently registered on the most vital of living substances, which is
“wax to receive and granite to retain,” nerve and brain being the next
best organs of registration only acting more specifically; while the
most generic resultants of experience attain their ultimate goal of
being recorded in the structure or functions of the germ plasm and thus
becoming permanent acquisitions of the species or race. On this view
the apex of life is reached at that stage of it when the influence of
the soma upon the germ plasm is greatest. This, of course, ceases when
the latter takes its departure with loss of the power to propagate.
Thus of all the stages of life, old age and its fortunes alone can
never affect heredity. Individuals who live on do so only by the
momentum given by germinal energies transmitted from their parents, and
only the old are completely isolated from the main currents of the life
of the race. They have already died racially or to the phylum and only
await a second or individual death. Thus if any large number of such
individuals lived on for many decades, they would be an encumbrance;
and so Nature, always intent on the interests of the species and so
indifferent to the individual, has to leave them to their fate. They
may still alleviate individual conditions but can contribute nothing to
racial memories in the above sense. The species has “forgotten them and
they are of it forgot.”
