[290] Professor Huxley goes on to say that the mechanist may, in turn, demand of the teleologist how the latter knows it was so intended. To this it may be replied he knows it as a necessary truth of reason deduced from his own primary intuitions, which intuitions cannot be questioned without _absolute_ scepticism. [291] The Professor doubtless means the _direct_ and _immediate_ result. (See Trans. Zool. Soc. vol. v. p. 90.) [292] "Natural Selection," p. 280. [293] Dr. Asa Gray, _e.g._, has thus understood Mr. Darwin. The Doctor says in his pamphlet, p. 38, "Mr. Darwin uses expressions which imply that the natural forms which surround us, because they have a history or natural sequence, could have been only generally, but not particularly designed,--a view at once superficial and contradictory; whereas his true line should be, that his hypothesis concerns the _order_ and not the _cause_, the _how_ and not the _why_ of the phenomena, and so leaves the question of design just where it was before." [294] "All science is but the partial reflexion in the _reason of man_, of the great all-pervading _reason of the universe_. And the _unity_ of science is the reflexion of the _unity_ of nature and of the _unity_ of that supreme reason and intelligence which pervades and rules over nature, and from whence all reason and all science is derived." (Rev. Baden Powell, "Unity of the Sciences," Essay i. Sec. ii. p. 81.) [295] "The Reign of Law," p. 40. [296] Though Mr. Darwin's epithets denoting design are metaphorical, his admiration of the result is unequivocal, nay, enthusiastic! [297] See "Habit and Intelligence," vol. i. p. 348. [298] The term, as before said, not being used in its ordinary theological sense, but to denote an immediate Divine action as distinguished from God's action through the powers conferred on the physical universe. [299] See "Natural Selection," pp. 332 to 360. [300] Loc. cit., p. 349. [301] See Professor Huxley's "Lessons in Elementary Physiology," p. 218. [302] It may be objected, perhaps, that excessive delicacy of the ear might have been produced by having to guard against the approach of enemies, some savages being remarkable for their keenness of hearing at great distances. But the perceptions of _intensity_ and _quality_ of sound are very different. Some persons who have an extremely acute ear for delicate sounds, and who are fond of music, have yet an incapacity for detecting whether an instrument is slightly out of tune.
