Why We Know
Have Keener
Smell? Hearing
and Touch
PROFESSOR CASH! SEASHORE,
the distinguished psychologist of
the State University of Iowa, has
Just furnished, through a series of interesting experiments, proof that no one of
the five senses pains integral power
through inactivity of any one or two of
the remaining four, but only seems to do
so because, in the absence of the others,
It is brought into larger use.
In other words, there is no reason why
the sense of touch of a blind man should
be keener than that, of a man of perfect
vision, if the latter "exercised" that sense
as much as constancy, former
Is compelled to do.
Our grandmothers are aware that,
blindness often so often leads to
sense of hearing and a touch that sounds
at a great distance, not audible to others,
would be distinctly heard by such person,
and that by the mere touch of their
finger-tips they could determine, in an
almost uncanny way, the qualities of various
 textures. Extraordinary keenness of
smell was attributed to persons defective
in some of the other senses, and even a
greater range of vision was sometimes
accredited to a man as a sort of compensation
or reward by nature for his being
railed upon to hear the burden of deafness.
Our grandmothers are now proven
to be wrong.
Man is born with several avenues leading
to a knowledge of external objects.  The eye seems to be the most convenient channel of approach to the outer world; therefore persons born with sight, vise the eye chiefly in apprehending objects.
