[2] Copulation would have sufficed for that. Life in common, after fertilization, is extremely rare, except among primates and birds. Among carnivorous insects, the union is often mortal for the male whom the stronger female devours.
Note.--Philosophic deductions are of value only if they agree exactly with science; but then they have a value. I have therefore availed myself of the opportunity to complete the note on a previous page, concerning the lie considered as a vital reaction. Here is the scientific statement of the question:
"M. R. Quinton has been led, in the course of his investigations, to recognize that all living beings are divided into two great physiological groups, which correspond exactly to the two anatomical groups: _Invertebrates_ and _Vertebrates_--The first, and lower group (Invertebrates), always in equilibrium with the environment, supporting all the exterior conditions, however unfavourable; the second, and higher (Vertebrates), not accepting these conditions, reacting against them, always in disequilibrium with the environment, maintaining internally the saline concentration of their origins, in opposition to the sea, which becomes more concentrated, or to fresh water which loses its salt; maintaining, moreover, its original temperature in opposition to a terrestrial environment which grows colder, _lying to the environment_, in short, in order to maintain its most favourable conditions of life. The lie, of which we speak, is only the psychological form of this reaction, on the part of the _Vertebrates_, against the hostility of the environment."
The obscure terms in this note (saline concentration, temperature of the origins) are explained in M. Quinton's book: _L'Eau de mer, milieu organique_.
STÉPHANE MALLARMÉ AND THE IDEA OF DECADENCE
Decadence: A very convenient word for ignorant pedagogues; a vague word behind which our laziness and lack of curiosity concerning the law seek shelter.
Abruptly, about 1885, the idea of decadence entered French literature. After serving to glorify or to ridicule a whole group of poets, it had perched, as it were, upon a single head. Stéphane Mallarmé was the prince of this ironical, almost injurious realm, as it would have been, had the word itself been rightly understood and employed. But, by an eccentricity which is a Latin trait, the academic world, in keeping with its normal but unwholesome horror when confronted with new tendencies, called thus the fever for originality which tormented a generation. M. Mallarmé, rendered responsible for the acts of rebellion which he had encouraged, appeared to the innocent ass-drivers who accompany but do not conduct the caravan a redoubtable Aladdin, assassin of the sound principles of universal imitation.
