good and evil, Mr. J. S. Mill expresses
himself thus: "My opinion of this doctrine is, that it is beyond all
others which now engage speculative minds, the decisive one between
moral good and evil for the Christian world." _Examination of Hamilton's
Philosophy_, p. 90.

to peruse the charming essay of Oersted, entitled _Das ganze Dasein Ein
Vernunftreich_.

[104-2] Herbert Spencer, _First Principles_, p. 112. Spinoza's famous
proposition, previously quoted, _Unaquaeque res quantum in se est, in suo
esse perseverare conatur_, (_Ethices, Pars III., Prop. VI._,) expresses
also the ultimate of modern investigation. A recent critic considers it
is a fallacy because the conatus "surreptitiously implies a sense of
effort or struggle for existence," whereas the logical concept of a res
does not involve effort (S. N. Hodgson, _The Theory of Practice_, vol.
I. pp. 134-6, London, 1870.) The answer is that identity implies
continuance. In organic life we have the fact of nutrition, a function
whose duty is to supply waste, and hence offer direct opposition to
perturbing forces.
