It is further to be considered that there are innumerable cases of contrivance, or evidence of design in nature, to which the principle of natural selection, or the purposeless changes effected by unconscious force, cannot apply; as for example, the distinction of sex, with all that is therein involved. But passing by such cases, it may be asked, what would it avail to get rid of design in the vegetable and animal kingdom, while the whole universe is full of it? That this ordered Cosmos is not from necessity or chance, is almost a self-evident fact. Not one man in a million of those who ever heard of God, either does doubt or can doubt it. Besides how are the cosmical relations of light, heat, electricity, to the constituent parts of the universe, and especially, so far as this earth is concerned, to vegetable and animal life, to be accounted for? Is this all chance work? Is it by chance that light and heat cause plants to carry on their wonderful operations, transmuting the inorganic into the organic, dead matter into living and life sustaining matter? Is it without a purpose that water instead of contracting, expands at the freezing point?--a fact to which is due that the earth north of the tropic is habitable for man or beast. It is no answer to this question to say that a few other substances have the same peculiarity, when no good end, that we can see, is thereby accomplished. No man is so foolish as to deny that his eye was intended to enable him to see, because he cannot tell what the spleen was made for. It is, however, useless to dwell upon this subject. If a man denies that there is design in nature, he can with quite as good reason deny that there is any design in any or in all the works ever executed by man.
