"The great thing,
then, in all education, is to make our nervous system
our ally instead of our enemy. . . For this we must make
automatic and habitual, as early as possible, as many
useful actions as we can . . . The more of the details
of our daily life we can hand over to the effortless custody of
automation, the more our higher powers of mind will be set free
for their own proper work."1a*
"The aim of
science is always to reduce complexity to simplicity .

are the metaphors by which it is most naturally described.
In talking of it hereafter, let us call it the
stream of thought, of
consciousness, or of
about a thing is knowledge of its relations.
In all our voluntary thinking there is some topic or
subject about which all the members of the thought revolve.
Relation, then, to our topic of interest is
constantly felt in the fringe, and particularly the relation of
harmony and discord, of furtherance or hindrance of the
what attention is. It is the taking possession by the mind,
in clear and vivid form, of one out of what seem several
simultaneously possible objects or trains of thought.
Focalization, concentration, of consciousness are of its essence.
It implies withdrawal from some things in order to deal
effectively with others . . ."1e

"A native talent
for perceiving analogies
is reckoned. . . as the
leading fact in genius of every order. . . I think I emphasize it
enough when I call it one of the ultimate foundation-pillars of
the intellectual life, the others being Discrimination,
Retentiveness, and Association."1g*
improvement of memory consists, then, in the improvement of
one's habitual methods of recording facts."1h*

"There are . . .
two ways of studying every psychic state. First, the way of
analysis: What does it consist in? What is its inner
nature? Of what sort of mind stuff is it composed? Second, the way
of history: What are the conditions of production, and its
connection with other facts?"2a
". . . the most
elementary single difference between the human mind
and that of brutes lies in this deficiency on the brute's
part to associate ideas by similarity . . ."2b*
attention is thus the essential phenomenon of will."2c
objects, compared in the same way, always give the same results
. . .
This last principle, which we may call the axiom of constant
result, holds good throughout all our mental operations

OF MEDIATE COMPARISON might be briefly . . . expressed by the
formula "more than the more is more
than the less" . . .
. . . This AXIOM OF SKIPPED INTERMEDIARIES or of
TRANSFERRED RELATIONS occurs . . . in logic as the
fundamental principle of inference . . . It seems to be on
the whole the broadest and deepest law of man's thought."2e*
"How could our
notion that one and one are eternally and necessarily
two ever maintain itself in a world where every time we add
one drop of water to another we get not two but one again? . .
. At most we could then say that one and one are usually

rationally intelligible throughout . . ."2g
