220 THE ESSENCE OF HUMANITY. 



aesthetic endowments in the cultivation, application, and 

 enjoyment of the arts and sciences.

 the pleasure felt in the proper contemplation and application 

 of them, are merely the adjuncts and aids to that higher 

 purpose of man's creation ; his continuous retention of a 

 knowledge of, and his obedient submission to God's moral 

 law, as involved in the principles of Christianity. 



14. The human constitution then involves in itself, and 

 secures for man, two guiding principles of action, not pos-

 the previous part of this lecture, I shall have to recur in sub- 

 sequent parts of the course ; and more particularly in my 

 three concluding lectures, in which I shall have to sum up 

 the results arrived at in the comparative anatomical portion 

 of the course. 



16. Such, then, are the conditions of man's life and welfare. 

 In my last lecture we found the conditions of the animal's 

 life and welfare were secured for it, in the fixed and un- 

 alterable working of its instinctive form of consciousness. 

 We shall now find that man, provided like the animal with 

 instinctive, corporeal, and cosmical conditions of life and 

 welfare, has superadded to his animal constitution a con-

 endowments. In the possession of this higher principle, 

 man is elevated above his own corporeal and instinctive in-
