LECTURE. 
Mr. President, Ladies and Gentlemen:-- 
We have met together to consider the best methods of Educating, that is, 
drawing out, or developing the Human Nature common to all of us. 
Truly a subject not easy to be exhausted. For we all of us feel that the 
Human Nature,--out of whose bosom has flowed all history, all science, 
all poetry, all art, all life in short,--contains within itself far more than 
that which has hitherto been manifested through all the periods of its 
history, though that history dates from the creation of the world, and 
has already progressed as far as the nineteenth century of the Christian 
era. Yes! we all of us feel that the land of promise lies far away in the 
future, that the goal of human history is yet a long way off. 
A large portion of this assembly consists of those whose business it is 
to study Human Nature in all its various forms, and who have taken 
upon themselves the task of developing that nature in the youth of 
America, in that rising generation whose duty it will be to carry out the 
nascent projects of reform in every department of human interest, and 
make the thought of to-day the fact of tomorrow. 
Some doubtless there are among this number, who by very nature are 
born Teachers, called to this office, as by a voice from heaven! Men,
who in spite of foolish detraction, or yet more foolish patronage, 
understand the dignity, the true nobility of their calling; who know that 
the 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 much 
what its Teachers intend, by God's blessing, to make it. 
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 
theme, some small portion of the nature and method of Human 
Development. 
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. 
Concerning these great divisions, I shall assert, first, that they are all 
mutually dependent upon each other; that if one of them suffer, all 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
