Accurately to sketch a doctrine such as this is a task of no slight difficulty. It undoubtedly contradicts the instinctive teaching of our consciousness, so that, as Professor Haeckel admits[166] in the primitive stages of both religion and philosophy Monism is unknown. Moreover, even those who most loudly profess it, have by no means as yet succeeded in realizing their own system, and after having from time to time formally enunciated its articles, proceed forthwith to ignore them, and in the staple of their discourse speak like other men in terms which have no meaning if the tenets of their creed have any. As a natural result their exposition of monistic doctrine is not very easy of apprehension, but it seems to be not unfairly reflected in the above summary.
Professor Haeckel himself thus expounds "that unifying conception of nature as a whole which we designate in a single word as Monism."[167]
By this we unambiguously express our conviction that[{129}] there lives "one spirit in all things," and that the whole cognizable world is constituted, and has been developed, in accordance with one common fundamental law. We emphasize by it, in particular, the essential unity of inorganic and organic nature, the latter having been evolved from the former only at a comparatively late period. We cannot draw a sharp line of distinction between these two great divisions of nature, any more than we can recognize an absolute distinction between the animal and the vegetable kingdom, or between the lower animals and man. Similarly, we regard the whole of human knowledge as a structural unity; in this sphere we refuse to accept the distinction usually drawn between the natural and the spiritual. The latter is only a part of the former (or vice versâ); both are one. Our monistic view of the world belongs, therefore, to that group of philosophical systems which from other points of view have been designated also as mechanical or as pantheistic.
More concisely and clearly, Professor Romanes tells us:[168]
Mental phenomena and physical phenomena, although apparently diverse, are really identical.
And in a work recently issued for the express purpose of expounding and diffusing the new gospel, we read:[169]
Just as the same particles of matter may at one time form parts of a rose, and at another time parts[{130}] of a mushroom, so the same force may at one time strike a church as lightning, and at another time may be the mother-love that rocks the cradle.
If such conceptions are not easy to grasp, there can be no doubt as to the practical conclusions to which they lead. We have already heard from Professor Haeckel that human freedom is an utter delusion. We have likewise seen that the only term in prospect is utter annihilation, which Professor Haeckel endeavours to persuade us is the consummation we ought to wish.
"The best we can desire," he says,[170] "after a courageous life, spent in doing good according to our light, is the eternal peace of the grave. 'Lord give them an eternal rest.'"
It is evident however that in order to secure such a reward it is not necessary to show any courage, or attempt any sort of good-work, for according to him it equally awaits the most selfish and abandoned voluptuary.
