simple apprehension, that to define it
would make it more obscure." {17} Definitions are useful where
things are new to us, but they are superfluous about those that are
already familiar, and mischievous, so far as they are possible at
all, in respect of all those things that enter so profoundly and
intimately into our being that in them we must either live or bear
no life. To vivisect the more vital processes of thought is to
suspend, if not to destroy them; for thought can think about
everything more healthily and easily than about itself. It is like
its instrument the brain, which knows nothing of any injuries
inflicted upon itself. As regards what is new to us, a definition
will sometimes dilute a difficulty, and help us to swallow that
which might choke us undiluted; but to define when we have once well
swallowed is to unsettle, rather than settle, our digestion.
Definitions, again, are like steps cut in a steep slope of ice, or
shells thrown on to a greasy pavement; they give us foothold, and
enable us to advance, but when we are at our journey's end we want
them no longer. Again, they are useful as mental fluxes, and as
helping us to fuse new ideas with our older ones. They present us
with some tags and ends of ideas that we have already mastered, on
to which we can hitch our new ones; but to multiply them in respect
of such a matter as thought, is like scratching the bite of a gnat;
the more we scratch the more we want to scratch; the more we define
the more we shall have to go on defining the words we have used in
our definitions, and shall end by setting up a serious mental raw in
the place of a small uneasiness that was after all quite endurable.
We know too well what thought is, to be able to know that we know
it, and I am persuaded there is no one in this room but understands
what is meant by thought and thinking well enough for all the
purposes of this discussion. Whoever does not know this without
words will not learn it for all the words and definitions that are
laid before him. The more, indeed, he hears, the more confused he
will become. I shall, therefore, merely premise that I use the word
"thought" in the same sense as that in which it is generally used by
people who say that they think this or that. At any rate, it will
be enough if I take Professor Max Muller's own definition, and say
that its essence consists in a bringing together of mental images
and ideas with deductions therefrom, and with a corresponding power
of detaching them from one another. Hobbes, the Professor tells us,
maintained this long ago, when he said that all our thinking
consists of addition and subtraction--that is to say, in bringing
ideas together, and in detaching them from one another.
