brain, as the arm, may show weariness when overtasked by the mind; 
may suffer waste of material, of phosphorus, if you please; but that will 
not prove mind to be brain, or brain mind. 
The all-transcending importance of this subject demands our yet further 
patient consideration. On the discrimination of the mind of man from 
the body and from the life, depends our truthful apprehension of the 
great problem of what we are, and what we are intended to be,—the most 
important consideration that can occupy the human mind. Can we, as 
rational beings, live over threescore years and ten, or more, and not de- 
vote much of our time to reflect upon this subject, the highest of philoso- 
phical studies? This is not an ‘‘ism’’ lying outside philosophical inquiry. 
No religion can begin her task, no philosophy can consummate her study, 
that has not persistently dwelt upon it and made it the theme of habitual 
thought. It is the necessary climax of all the study that can give us the 
solution of the problem of the universe. In this age of materialistic skep- 
ticism, that respects no time-honored opinions, or sacred traditions, we 
must begin where the physicists begin, but may not stop where they are 
wont to stop; may not refuse to know the ultimate significance of all 
created things and beings, body and soul, as they are constantly presented 
before our senses, and demand interpretation from our reasoning intellect. 
We may not fail to examine and consider all the true facts that the natu- 
ralist and physicist make the basis of their theories, nor all other facts 
that must be taken into view, for a true solution of the problem. No «@ 
priori assumptions may be admitted as bases of induction; and it must not 
be allowed the skeptic to say, as he is sure to do, that he only builds truly 
upon certain facts ; that his faith alone stands in inductive truth ; that 
religious faith will not bear the test of induction from asertained facts. 
And we must not permit him to make his inductions from less than half 
the facts that define our being, and these the less important. 
The mind’s thoughts are not propagated as things of physical growth. 
We but borrow, in relation to the mind, the language of the garden, and 
use it figuratively, when we speak of sowing mental seeds, or propagating 
ideas. The thoughts I am speaking, I do not lose ; and your gain, if any, 
is not a material acquisition; nor, so far as you or I can ever know, has 
the effect been produced by molecular changes in our brains ; and if 
such changes do take place, they are a life process of the brain, and can- 
not, conceivably to us, be the thoughts that enter into and exercise your 
minds; thoughts that, as believed worthy, or as your minds may make 
them worthy, may become permanently your thoughts, after the mo- 
lecular particles moved, if any such, will have long passed away. The 
mind may, indeed, for aught we know, and we may so conjecture it prob- 
able, put the brain in motion, as we know it will thrill the nerves, and 
can hurry the blood ; as the wind can heave the water into waves, but the 
cause and the effect are different, and continue ever after as distinct as 
before. 
Physiology teaches us that the mind is seated in the brain ; for with the
