Certain animal psychologists, however, refuse to reserve the prerogative of intelligence for man. Bouvier’s “La Vie Psychique des Insectes” (1918), for example, contains the following statement: “Choice of a remarkably intellectual nature, is even more noticeable in the instinctive manifestations of individual memory. The animal, endowed with well-developed senses and nervous system, not only reacts to new necessities by new acts, but associates the stored up impressions of new sensations and thereby appropriately directs its further activities. Thus, by an intelligent process, new habits are established, which by heredity become part of the patrimony of instinct, modifying the latter and constituting elements essential to its evolution. Of these instincts acquired through an intelligent apprenticeship Forel was led to say that they are reasoning made automatic, and it is to them particularly that we may apply the idea of certain biologists that instincts are habits which have become hereditary and automatic.” (Smithson. Inst. Rpt. for 1918, p. 454.) It is extremely doubtful, however, whether Bouvier is here using the term intelligence in its proper sense. Indeed, his words convey the impression that what he means by intelligence is an _ability to profit by experience_. Now, ability to profit by experience may, under one set of circumstances, involve the power of logical reflection and inference, while, under another set of circumstances, it may imply nothing more than the power of associative memory. In the latter case, the facts are explicable without any recourse to psychic powers of a superorganic nature, and, in point of fact, it often happens that the very zoöpsychologists, who insist on attributing this sort of “intelligence” to brutes, are most emphatic in denying that brutes are endowed with _reason_. In any case, it is unfortunate that the word intelligence is now used in two entirely different senses. This new and improper sense, being unrelated to the etymology, and out of harmony with the accepted use of the term, serves only to engender a confusion of ideas. It should be suppressed, in order to avoid misunderstandings.
