Now, if there is one view more prominent than another in Mr Darwin's work, it is embodied in the phrase to which he has given a new sense and significance, "the struggle for existence." In the midst of this struggle for existence, what is there in the greatest happiness principle to bind the individual to abnegation? Why should he postpone his certain and immediate gratification to the remote advantage of others, or of distant and contingent advantage to himself? If, on the other hand, he regards the transitoriness of the enjoyment, and balances it against the fixity and eternity of the consequences, the argument takes altogether different proportions, and the temptation to enjoyment is inversely to the intensity of the struggle for existence. I will take another test of Benthamism by Darwinism, which will more exactly bring out the argument for which I contend. We have a traditional horror of infanticide which revolts all our best feelings and shocks our principles. But if Mr Darwin has demonstrated this struggle for existence existing from all time; if also we are disembarrassed from all advertence to another world; if, further, Mr Malthus, before Mr Darwin, has shown reason to believe that over-population is the cause of half the evils of this life, what is there in Benthamite principles which should prevent our sacrificing these unconscious innocents to the greatest happiness of the greatest number? Nothing, except the horror we should excite among mankind still imbued with the old superstitions! A person who did not hold to Mr Malthus' views might demur; but a Malthusian, who was also a disciple of Mr Bentham, could only hold back because his feelings were better than his principles. A disciple of Mr Darwin's would probably stand aloof, and would merely see in our notions an artificial interference with the working of his theory, preventing the struggle for existence going on according to natural laws. This seems to me to be almost said in the same article from the _Pall Mall Gazette_, from which I have quoted. Mr Darwin, in his "Origin of Species" (p. 249), has pointed out that "we ought to admire the savage instinct which leads the queen-bee to destroy her young daughters as soon as born, because this is for the good of the community." And in his new book he says, firmly and unmistakably (i. 73), that "if men were reared under precisely the same conditions as hive-bees, there can hardly be a doubt that our unmarried females would, like the worker-bees, think it a sacred duty to kill their brothers, and mothers would strive to kill their fertile daughters, and no one would think of interfering."
