favour of the existence in every animal of an immaterial principle similar to that which by its excellence and superior endowments places man so much above animals; yet the principle unquestionably exists, and whether it be called sense, reason, or instinct, it presents in the whole range of organised beings a series of phenomena closely linked together, and upon it are based not only the higher manifestations of the mind, but the very permanence of the specific differences which characterise every organism. Most of the arguments in favour of the immortality of man apply equally to the permanency of this principle in other living beings. May I not add that a future life in which man would be deprived of that great source of enjoyment and intellectual and moral improvement which results from the contemplation of the harmonies of an organic world would involve a lamentable loss? And may we not look to a spiritual concert of the combined worlds and all their inhabitants in the presence of their Creator as the highest conception of paradise?"—'Essay on Classification,' sect, xvii. p. 97–99.
