SCIENCE. 



For the present I must bring these papers to a close. 

 If the conclusions to which they point are true, then we 

 have in them some foundation-stones strong enough to 

 bear the weight of an immense, and, indeed, of an im- 

 measurable, superstructure. If the Unity of Nature is 

 not a unity which consists in mere sameness of mate- 

 rial, or in mere identity of composition, or in mere uni- 

 formity of structure, but a unity which the mind recog- 

 nizes as the result of operations similar to its own ; if 

 man, not in his body only, but in the highest as well as 

 in the lowest attributes of his spirit, is inside this Unity 

 and part of it ; if all his powers are, like the instincts 

 of the beasts, founded on a perfect harmony between his 

 faculties and the realities of creation; if the limits of his 

 knowledge do not affect its certainty ; if its accepted 

 truthfulness in the lower fields of thought arises out of 

 correspondences and adjustments which are applicable 

 to all the operations of his intellect, and all the energies 

 of his spirit ; if the moral character of Man, as it exists 

 now, is the one great anomaly in Nature — the one great 

 exception to its order and to the perfect harmony of its 

 laws ; if the corruption of this moral character stands in 

 immediate and necessary connection with rebellion 

 against the Authority on which that order rests ; if all 

 ignorance and error and misconception respecting the 

 nature of that Authority and of its commands has been 

 and must be the cause of increasing deviation, disturb- 

 ance, and perversion, then, indeed, we have a view of 

 things which is full of light. Dark as the difficulties 

 which remain may be, they are not of a kind to under- 

 mine all certitude, to discomfit all conviction, and to dis- 

 solve all hope. On the contrary, some of these difficul- 

 ties are seen to be purely artificial ard imaginary, 



whilst many others are exposed to the suspicion of be- 

 longing to the same class and category. In some cases 

 our misgivings are shown to be unreasonable, whilst in 

 many other cases, to say th£ least, doubt is thrown on 

 Doubt. Let destructive criticism do its work. But let 

 that work be itself subjected to the same rigid analysis 

 which it professes to employ. Under the analysis, unless 

 I am much mistaken, the destroyer will be destroyed. 

 That which pretends to be the universal solvant of all 

 knowledge and of all belief, will be found to be destitute 

 of any power to convict of falsehood the universal in- 

 stinct of Man, that by a careful and conscientious use of 

 the appropriate means he can, and does, attain to a sub- 

 stantial knowledge of the Truth.
