212 Instinct. 



And the assertion, which we now make, that man 

 has a wider range of Instinct than any other animal 

 on the globe, may be regarded as another attempt 

 to break down the distinction, upon which we pride 

 ourselves. We make no attempt to break down 

 distinctions. We wish to find them, where nature 

 has placed them, — as we mark distinctions in a nat- 

 ural classification, — and not to invent distinctions, 

 or make them where they only seem to exist, on 

 account of some accidental characteristic, as is done 

 in artificial systems of classification. 



If man has, in him, something higher than an 

 animal, it does not destroy his animal nature ; but 

 it is something added to that nature. This animal 

 nature of man, we are first to consider ; for it is an 

 essential part of us, while we remain in this world. 

 We have already shown that the bodies of the high- 

 er animals are essentially the same as those of men. 

 The bones, and muscles, and nerves, in both corre- 

 spond ; modified only according to the habits of 

 each. We are of the earth, as well as they. We 

 have no element, in our bodies, not found in theirs. 

 Our bodies are subject to the same laws as theirs, 

 in every respect, except as they have given to them 

 certain changes of activities, to fit them for special 

 modes of life, as in the case of hibernation. We 

 find in ourselves, no new law of physiology. Every 

 effort costs the waste of tissue, in the ox which 

 turns the furrow, and in the husbandman, who 

 holds the plough. Hunger, thirst, weariness and 

 sleep come to both alike. That the human body 

 is all animal, there can be no doubt. And, as an
