Religion
by Charles Darwin
"Everyone believing, as I do, that all the
corporeal and mental organs (excepting those which
are neither advantageous nor disadvantageous to the
possessor) of all beings have been developed
through natural selection, or the survival of the
fittest, together with use or habit, will admit
that these organs have been formed so that their
possessors may compete successfully with other
beings, and thus increase in number. Now an animal
may be led to pursue that course of action which is
most beneficial to the species by suffering, such
as pain, hunger, thirst, and fear; or by pleasure,
as in eating and drinking, and in the propagation
of the species, &c.; or by both means combined,
as in the search for food. But pain or suffering of
any kind, if long continued, causes depression and
lessens the power of action, yet is well adapted to
make a creature guard itself against any great or
sudden evil. Pleasurable sensations, on the other
hand, may be long continued without any depressing
effect; on the contrary, they stimulate the whole
system to increased action. Hence it has come to
pass that most or all sentient beings have been
developed in such a manner, through natural
selection, that pleasurable sensations serve as
their habitual guides. We see this in the pleasure
from exertion, even occasionally from great
exertion of the body or mind, -- in the pleasure of
our daily meals, and especially in the pleasure
derived from sociability, and from our loving
families. The sum of such pleasures as these, which
are habitual or frequently recurrent, give, as I
can hardly doubt, to most sentient beings an excess
of happiness over misery, although many
occasionally suffer much. Such suffering is quite
compatible with the belief in Natural Selection,
which is not perfect in its action, but tends only
to render each species as successful as possible in
the battle for life with other species, in
wonderfully complex and changing circumstances.
"That there is much suffering in the world no
one disputes. Some have attempted to explain this
with reference to man by imagining that it serves
for his moral improvement. But the number of men in
the world is as nothing compared with that of all
sentient beings, and they often suffer greatly
without any moral improvement. This very old
argument from the existence of suffering against
the existence of an intelligent First Cause seems
to me a strong one; whereas, as just remarked, the
presence of much suffering agrees well with the
view that all organic beings have been developed
through variation and natural selection.
"At the present day the most unusual argument
for the existence of an intelligent God is drawn
from the deep inward conviction and feelings which
are experienced by most persons.
"Formerly I was led by feelings such as those
just referred to (although I do not think that the
religious sentiment was ever strongly developed in
me), to the firm conviction of the existence of
Gold and of the immortality of the soul. In my
Journal I wrote that whilst standing in the midst
of the grandeur of a Brazilian forest, 'it is not
possible to give an adequate idea of the higher
feelings of wonder, admiration, and devotion which
fill and elevate the mind.' I well remember my
conviction that there is more in man than the mere
breath of his body; but now the grandest scenes
would not cause any such convictions and feelings
to rise in my mind. It may be truly said that I am
like a man who has become color-blind, and the
universal belief by men of the existence of redness
makes my present loss of perception of not the
least value as evidence. This argument would be a
valid one if all men of all races had the same
inward conviction of the existence of one God; but
we know that this is very far from being the case.
Therefore I cannot see that such inward convictions
and feelings are of any weight as evidence of what
really exists. The state of mind which grand scenes
formerly excited in me, and which was intimately
connected with a belief in God, did not essentially
differ from that which is often called the sense of
sublimity; and however difficult it may be to
explain the genesis of this sense, it can hardly be
advanced as an argument for the existence of God,
any more than the powerful though vague and similar
feelings excited by music.
"With respect to immortality, nothing shows me
[so clearly] how strong and almost
instinctive a belief it is as the consideration of
the view now held by most physicists, namely, that
the sun with all the planets will in time grow too
cold for life, unless indeed some great body dashes
into the sun and thus gives it fresh life.
Believing as I do that man in the distant future
will be a far more perfect creature than he now is,
it is an intolerable thought that he and all other
sentient beings are doomed to complete annihilation
after such long-continued slow progress. To those
who fully admit the immortality of the human soul,
the destruction of our world will not appear so
dreadful."
