This is like saying, “It is not true that such and such a picture was rejected for the Academy, but it is true that it was submitted to the President and Council of the Royal Academy, with a view to acceptance at their next forthcoming annual exhibition, and that the President and Council regretted they were unable through want of space, &c., &c.”—and as much more as the reader chooses. I shall venture, therefore, to stick to it that the octogenarian was once a fish, or if Professor Huxley prefers it, “an organism which must be classified among fishes.” But if a man was a fish once, he may have been a fish a million times over, for aught he knows; for he must admit that his conscious recollection is at fault, and has nothing whatever to do with the matter, which must be decided, not, as it were, upon his own evidence as to what deeds he may or may not recollect having executed, but by the production of his signatures in court, with satisfactory proof that he has delivered each document as his act and deed. This made things very much simpler. The processes of embryonic development, and instinctive actions, might be now seen as repetitions of the same kind of action by the same individual in successive generations. It was natural, therefore, that they should come in the course of time to be done unconsciously, and a consideration of the most obvious facts of memory removed all further doubt that habit—which is based on memory—was at the bottom of all the phenomena of heredity. I had got to this point about the spring of 1874, and had begun to write, when I was compelled to go to Canada, and for the next year and a half did hardly any writing. The first passage in “Life and Habit” which I can date with certainty is the one on page 52, which runs as follows:— “It is one against legion when a man tries to differ from his own past selves. He must yield or die if he wants to differ widely, so as to lack natural instincts, such as hunger or thirst, and not to gratify them. It is more righteous in a man that he should ‘eat strange food,’ and that his cheek should ‘so much as lank not,’ than that he should starve if the strange food be at his command. His past selves are living in him at this moment with the accumulated life of centuries. ‘Do this, this, this, which we too have done, and found out profit in it,’ cry the souls of his forefathers within him. Faint are the far ones, coming and going as the sound of bells wafted on to a high mountain; loud and clear are the near ones, urgent as an alarm of fire.”
