that God's existence is limited and controlled in a thousand ways. Nor does this argument show that God always existed; at the best the proof is only that some cause, enough for the effect, existed before it, but there is no evidence that this cause differs from any other causes, which are often as transient as the effect itself. And as it does not demonstrate that God has always existed, neither does it demonstrate that he will always exist, or even that he now exists. It is perfectly in accordance with the argument, and with the analogy of cause and effect, that the effect may remain after the cause has ceased to exist. Nor does the argument from design demonstrate one God. It is quite consistent with this argument that a separate cause existed for each effect, or mark of design discovered, or that several causes contributed to some or one of such effects. So that if the argument be true, it might result in a multitude of petty deities, limited in knowledge, extent, duration, and power; and still worse, each one of this multitude of gods may have had a cause which would also be finite in extent and duration, and would require another, and so on, until the design argument loses the reasoner amongst an innumerable crowd of deities, none of whom can have the attributes claimed for God.
The design argument is defective as an argument from analogy, because it seeks to prove a Creator God who designed, but does not explain whether this God has been eternally designing, which would be absurd; or, if he at some time commenced to design, what then induced him so to commence. It is illogical, for it seeks to prove an immutable Deity, by demonstrating a mutation on the part of Deity.
It is unnecessary to deal specially with each of the many writers who have used from different stand-points the a posteriori form of argument in order to prove the existence of Deity. The objections already stated apply to the whole class; and, although probably each illustration used by the theistic advocate is capable of an elucidation entirely at variance with his argument, the main features of objection are the same. The argument a posteriori is a method of proof in which the premises are composed of some position of existing facts, and the conclusion asserts a position antecedent to those facts. The argument is from given effects
