You will understand this better, perhaps, if I give you some familiar
example. You have all heard it repeated, I dare say, that men of science
work by means of induction and deduction, and that by the help of these
operations, they, in a sort of sense, wring from Nature certain other
things, which are called natural laws, and causes, and that out of
these, by some cunning skill of their own, they build up hypotheses and
theories. And it is imagined by many, that the operations of the common
mind can be by no means compared with these processes, and that they
have to be acquired by a sort of special apprenticeship to the craft.
To hear all these large words, you would think that the mind of a man of
science must be constituted differently from that of his fellow men; but
if you will not be frightened by terms, you will discover that you are
quite wrong, and that all these terrible apparatus [87] are being used
by yourselves every day and every hour of your lives.
There is a well-known incident in one of Moliere's plays,[88] where the
author makes the hero express unbounded delight on being told that he
had been talking prose during the whole of his life. In the same way, I
trust, that you will take comfort, and be delighted with yourselves, on
the discovery that you have been acting on the principles of inductive
and deductive philosophy during the same period.
