The
Entangled Bank There is grandeur in this view of life.
During
early periods of the earths history, when the forms of life
were probably fewer and simpler, the rate of change was probably
slower; and at the first dawn of life, when very few forms of the
simplest structure existed, the rate of change may have been slow
in an extreme degree. The whole history of the world, as at present
known, although of a length quite incomprehensible by us, will hereafter
be recognized as a mere fragment of time, compared with the ages
which have elapsed since the first creature, the progenitor of innumerable
extinct and living descendants, was created.
In
the distant future I see open fields for far more important researches.
Psychology will be based on a new foundation, that of the necessary
acquirement of each mental power and capacity by gradation. Light
will be thrown on the origin of man and his history
It
is interesting to contemplate an entangled bank, clothed with many
plants of many kinds, with birds singing on the bushes, with various
insects flitting about, and with worms crawling through the damp
earth, and to reflect that these elaborately constructed forms,
so different from each other, and dependent on each other in so
complex a manner, have all been produced by laws acting around us.
These
laws, taken in the largest sense, being Growth with Reproduction;
Inheritance which is almost implied by reproduction; Variability
from the indirect and direct action of the external conditions of
life, and from use and disuse; a Ratio of Increase so high as to
lead to a Struggle for Life, and as a consequence to Natural Selection,
entailing Divergence of Character and the Extinction of less-improved
forms.
Thus,
from the war of nature, from famine and death, the most exalted
object which we are capable of conceiving, namely, the production
of the higher animals, directly follows.
There
is grandeur in this view of life, with its several powers, having
been originally breathed into a few forms or into one; and that,
whilst this planet has gone cycling on according to the fixed law
of gravity, from so simple a beginning endless forms most beautiful
and most wonderful have been, and are being, evolved.
