"The question of whether it is better to abide quiet, and take advantage of opportunities that come, or to go farther afield in search of them, is one of the oldest which living beings have to deal with. It was on this that the first great schism or heresy arose in what was heretofore the catholic faith of protoplasm. The schism still lasts, and has resulted in two great sects--animals and plants. The opinion that it is better to go in search of prey is formulated in animals; the other--that it is better, on the whole, to stay at home, and profit by what comes--in plants. Some intermediate forms still record to us the long struggle during which the schism was not yet complete. "If I may be pardoned for pursuing this digression further, I would say that it is the plants, and not we, who are the heretics. There can be no question about this; we are perfectly justified, therefore, in devouring them. Ours is the original and orthodox belief, for protoplasm is much more animal than vegetable. It is much more true to say that plants have descended from animals than animals from plants. Nevertheless, like many other heretics, plants have thriven very fairly well. There are a great many of them, and, as regards beauty, if not wit--of a limited kind, indeed, but still wit--it is hard to say that the animal kingdom has the advantage. The views of plants are sadly narrow; all dissenters are narrow-minded; but within their own bounds they know the details of their business sufficiently well--as well as though they kept the most nicely-balanced system of accounts to show them their position. They are eaten, it is true; to eat them is our intolerant and bigoted way of trying to convert them: eating is only a violent mode of proselytizing, or converting; and we do convert them--to good animal substance of our own way of thinking. If we have had no trouble we say they have 'agreed' with us; if we have been unable to make them see things from our point of view, we say they 'disagree' with us, and avoid being on more than distant terms with them for the future. If we have helped ourselves to too much, we say we have got more than we can 'manage.' And an animal is no sooner dead than a plant will convert it back again. It is obvious, however, that no schism could have been so long successful without having a good deal to say for itself.
