rapid process that overleaps intermediate steps, which is our guide in
the numerous decisions that we are called to make in our every-day life,
and which perceives, in a somewhat vague and indefinite manner--becomes
our only guide in this Realm of the Inexact.

The advent of a Unitary Science and the inauguration of a true Deductive
Method in all domains of Thought, will, indeed, completely revolutionize
our Scientific bases, and render precision and infallibility possible in
domains where now only conjecture and probability exist. It will enable
us to establish on a firm and secure foundation the _Laws or Principles
of every department of the Universe of Matter and of Mind_, and to
penetrate the Phenomena of all realms to an extent now scarcely
imagined. It will furnish us the 'Criterion of Truth' so long sought
after--a ground of intellectual agreement in all the concerns of life,
so far as this is essential, similar to that which we now have in
Mathematics, where difference of opinion is impossible because _proof is
of a nature to be alike convincing to all_.

But, as in Mathematics a limit is reached, beyond which the finite
character of our intelligence does not permit us to _apply_ the Laws
which we are well assured still prevail, so there is an outlying circle
of practical activity which no Science can compass. The various tints of
the autumn forest are probably the results of Mathematical arrangements
of particles; but to how great an extent we shall be able to discover
what precise arrangement produces a given shade of color, is doubtful.
Some delicate varieties, at least, will always be beyond our definite
apprehension. Whether we shall dine at one hour or another, whether we
will wear gray or black, and innumerable other questions of specialty,
do not come within the range of Scientific solution, and never can. So
that when every domain of human concern is solidly established on a
