lo! the telephone became the
world's nervous system, and aeroplanes began to multiply like summer
flies. To common sense the alchemist's dream of transmuting lead
into gold seems preposterous, yet in a hundred laboratories radium
is breaking down into helium, and the new chemistry bids fair to
turn the time-honored jeer at the alchemists completely upside down.
A wife whose mind was oriented in the new direction effectually
silenced her husband's ridicule of what he called her credulity by
reminding him that when wireless telegraphy was first suggested he
had exclaimed, "Ah, that, you know, is one of the things that is not
possible!" He was betrayed by his common sense.
The lessons such things teach us are summed up in the reply of Arago,
the great savant, to the wife of Daguerre. She asked him if he
thought her husband was losing his mind because he was trying to
make permanent the image in a mirror. Arago is said to have answered,
"He who, outside of pure mathematics, says a thing is impossible,
speaks without reason."
Common sense neither leads nor lags, but is ever limited to the
passing moment: the common knowledge of to-day was the mystery and
enchantment of the day before yesterday, and will be the mere
commonplace of the day after to-morrow. If common sense can so
little anticipate the ordinary and orderly advancement of human
knowledge, it is still less able to take that leap into the dark
which is demanded of it now. The course of wisdom is therefore to
place reliance upon reason and intuition, leaving to common sense
the task of guiding the routine affairs of life, and guiding these
alone.
THE FUNCTION OF SCIENCE
In enlisting the aid of reason in our quest for freedom, we shall be
following in the footsteps of mathematicians and theoretical
physicists. In their arduous and unflinching search after truth they
have attained to a conception of the background of phenomena of far
greater breadth and grandeur than that of the average religionist of
to-day. As a mathematician once remarked to a neo-theosophist,
"Your idea of the ether is a more material one than the materialist's
own." Science has, however, imposed upon itself its own limitations,
and in this connection these should be clearly understood.
Science is that knowledge which can be gained by exact observation
and correct thinking. If science makes use of any methods but these
it ceases to be itself. Science has therefore nothing to do with
