office of the teacher is coëval with the world; and also feel with true
prophetic foresight, that the world, fifty years hence, will be very

Brothers in a high calling! The speaker, proudly enrolling himself in
the number of your noble band, greets you from his heart this day, and
invites you to spend a thoughtful hour with him; and to help him, by
your best wishes, to unfold in a manner not wholly unworthy of his

Ours is the age of analysis. We begin to see that before we can
understand a substance, it is necessary to become acquainted with all
its component parts. Thus, then, with regard to Human Nature, we must
understand all at least of its grand divisions, before we can comprehend
the method of developing it as a whole.

Let us then say, that there are five grand divisions in Human
Nature,--the physical, the intellectual, the affectional, the moral, and
the devotional,--or in other words, that man has body, mind, heart,
conscience, and soul.

the others suffer with it; that man is dwarfed and incomplete, unless he
is fully developed in all the five: and, _secondly_, as my special
subject, I maintain that physical well-being, health of body, is
therefore necessary not only to the complete development of Human
Nature, but that it is also essential to a happy and harmonious
development of each one of the four other great divisions of Human
