The Reign of Law has gradually crept into every department of Nature, transforming knowledge everywhere into Science. The process goes on, and Nature slowly appears to us as one great unity, until the borders of the Spiritual World are reached.
It is impossible to believe that the amazing successions of revelations in the domain of Nature, during the last few centuries, at which the world has all but grown tired wondering, are to yield nothing for the higher life.
If we neglect almost any of the domestic animals, they will rapidly revert to wild and worthless forms. Now, the same thing exactly would happen in the case of you or me. Why should man be an exception to any of the laws of nature?
To go outside what we call Nature is not to go outside Environment. Nature, the natural Environment, is only a part of Environment. There is another large part, which, though some profess to have no correspondence with it, is not on that account unreal, or even unnatural. The mental and moral world is unknown to the plant. But it is real.
We fail to praise the ceaseless ministry of the great inanimate world around us only because its kindness is unobtrusive. Nature is always noiseless. All her greatest gifts are given in secret. And we forget how truly every good and perfect gift comes from without, and from above, because no pause in her changeless beneficence teaches us the sad lessons of deprivation.
The Life of the senses, high and low, may perfect itself in Nature. Even the Life of thought may find a large complement in surrounding things. But the higher thought, and the conscience, and the religious Life, can only perfect themselves in God.
The work begun by Nature is finished by the Supernatural--as we are wont to call the higher natural. And as the veil is lifted by Christianity it strikes men dumb with wonder. For the goal of Evolution is Jesus Christ.
