CHAPTER VIII Instinct Instincts comparable with habits, but different in their origin—In- stincts graduated—Aphides and ants—Instincts variable—Do- mestic instincts, their origin—Natural instincts of the cuckoo, molothrus, ostrich, and parasitic bees—Slave-making ants—Hive- bee, its cell-making instinct—Changes of instinct and structure not necessarily simultaneous—DifBculties of the theory of the Natural Selection of instincts—Neuter or sterile insects— Summary. MANY instincts are so wonderful that their develop- ment will probably appear to the reader a diflficulty sufficient to overthrow my whole theory. I may here premise, that I have nothing to do with the origin of the mental powers, any more than I have ^vith that of life itself. We are concerned only with the diversities of instinct and of the other mental faculties in animals of the same class. I will not attempt any definition of instinct. It would be easy to show that several distinct mental actions are com- monly embraced by this term; but every one understands what is meant, when it is said that instinct impels the cuckoo to migrate and to lay her eggs in other birds' nests. An ac- tion, which we ourselves require experience to enable us to perform, when performed by an animal, more especially by a very young one, without experience, and when performed by many individuals in the same way, without their knowing for what purpose it is performed, is usually said to be in- stinctive. But I could show that none of these characters are universal. A little dose of judgment or reason, as Pierre Huber expresses it, often comes into play, even with animals low in the scale of nature.
