There are conditions under which circumstantial evidence is the best
possible testimony. These conditions are found inseparably connected
with our present subject. That men now possess the same powers of body
and mind that they always manifested is disputed by no intelligent
individual. Those powers have been, through all the ages, precisely the
same both in number and kind. Has the history of humanity furnished a
single case in which a person, perfectly deaf during all his life, had
the ability to speak words? Such is unknown in the history of the past,
and also in the records of the present. History is as blank at this
point, as a barren oasis. All the other faculties are as perfect with
the deaf as they are with those whose hearing is perfect. Their
inventive genius is equally vigorous; this being true, why should the
defect of the ear deprive them of the power of speech? Will the Deist
answer this question? Mr. Skeptic, as you are in the same difficulty
with the Deist, you may help him if you choose. If you are, as you
pretend, free and fearless thinkers, give us your thoughts upon this
question. If you are cowardly, then stand off and sneer at the question
which you dare not try to answer. The facts developed at this point
ought to be remembered, and the question, why can the deaf, described,
never talk? ought to be pressed home to every heart.
