What we want to know definitely from science is: How does this thing
which I call my mind work? Science regards mind as the sum of
sensations, which are the necessary results of antecedent causes. It
endeavours to know how and in what way these sensations can be trained
and perfected. Nearly twenty years ago, a writer in the Psychological
Journal "Mind"[1] Mr. J. Jacobs, attempted to form a Society for the
purpose of experimental psychology. Thinkers and scientific men have
carried out this work, but the general public has not been greatly
interested or interested for any length of time. No such society
exists among the English public. The greater number of enthusiastic
students is to be found in Italy and America. But Germany has
furnished great individual workers, such as Fechner, Helmholtz, and
Wundt. Collective investigation was necessary to separate individual
peculiarities from general laws. Science of course aims at changing
the study of individual minds/into "a valid science of mind." Mr. J.
Jacobs wished a Society to be organised for the purpose of measuring
mind, measuring our senses, and for testing our mental powers as
accurately as weight and height are tested now, and also for
experimenting on will practice. He believed it possible to train the
will on one thing until we got it perfectly under control, and in so
doing we should modify character immensely. If this proved possible,
we ought to persevere until conduct becomes an art, education a
principle, and mind is known as a science is known. Mr. Jacobs wanted
systematic enquiries to be made into powers of attention, such as "Can
we listen and read at the same time, and reproduce what we have read
and heard." And into the faculties of observation and memory, with
after images, and the capacity for following trains of reasoning,
&c., &c., "When we read a novel, do we actually have pictures of the
scenes before our minds?" Mr. Jacobs wished for enquiries into every
kind of intelligence ordinary and extraordinary; out of all
ingredients of character, out of early impressions, out of classified
emotions to build up an answer to the question: "Is there a science
of mind?" Since he wrote, much has been done in experiment by the
scientific. Children's minds are constantly being investigated, and
the results given to the public. Mr. Galton has to some extent
