(1) “Are intelligence and instinct, thus differing in their relative proportion in man as compared with all other animals, yet the same in kind and manner of operation in both? To this question we must give at once an affirmative answer. The expression of Cuvier, regarding the faculty of reasoning in lower animals, ‘Leur intelligence execute des operations du meme genre,’ is true in its full sense. We can in no manner define reason so as to exclude acts which are at every moment present to our observation, and which we find in many instances to contravene the natural instincts of the species. The demeanour and acts of the dog in reference to his master, or the various uses to which he is put by man, are as strictly logical as those we witness in the ordinary transactions of life.”—Sir Henry Holland, chapters on “Mental Physiology,” p. 220.
The whole of the chapter on Instincts and Habits in this work should be read in connection with the passage just quoted. The work itself, at once cautious and suggestive, is not one of the least obligations which philosophy and religion alike owe to the lucubrations of English medical men.

(4) M. Tissot the distinguished Professor of Philosophy at Dijon, in his recent work, “La Vie dans l’Homme,” p. 255, gives a long and illustrious list of philosophers who assign a rational soul (ame) to the inferior animals, though he truly adds, “that they have not always the courage of their opinion.”
(5) Some idea of the extent of research and imagination bestowed on this subject may be gleaned from the sprightly work of Pierquin de Gemblouz, “Idiomologie des Animaux,” published at Paris, 1844.

Perhaps I should observe, that here and elsewhere in the dialogues between Faber and Fenwick, it has generally been thought better to substitute the words of the author quoted for the mere outline or purport of the quotation which memory afforded to the interlocutor.
