This incapacity of the imagination to reconstruct the conditions of life and build the frame of things nearer to the heart's desire is dangerous to a steady loyalty to what is noble and fine. We surrender ourselves to a kind of miscellaneous appreciation, without standard or goal; and calling every vexatious apparition by the name of beauty, we become incapable of discriminating its excellence or feeling its value. We need to clarify our ideals, and enliven our vision of perfection. No atheism is so terrible as the absence of an ultimate ideal, nor could any failure of power be more contrary to human nature than the failure of moral imagination, or more incompatible with healthy life. For we have faculties, and habits, and impulses. These are the basis of our demands. And these demands, although variable, constitute an ever-present intrinsic standard of value by which we feel and judge. The ideal is immanent in them; for the ideal means that environment in which our faculties would find their freest employment, and their most congenial world. Perfection would be nothing but life under those conditions. Accordingly our consciousness of the ideal becomes distinct in proportion as we advance in virtue and in proportion to the vigour and definiteness with which our faculties work. When the vital harmony is complete, when the _act_ is _pure,_ faith in perfection passes into vision. That man is unhappy indeed, who in all his life has had no glimpse of perfection, who in the ecstasy of love, or in the delight of contemplation, has never been able to say: It is attained. Such moments of inspiration are the source of the arts, which have no higher function than to renew them. A work of art is indeed a monument to such a moment, the memorial to such a vision; and its charm varies with its power of recalling us from the distractions of common life to the joy of a more natural and perfect activity. _The stability of the ideal._ Sec. 66. The perfection thus revealed is relative to our nature and faculties; if it were not, it could have no value for us. It is revealed to us in brief moments, but it is not for that reason an unstable or fantastic thing. Human attention inevitably flickers; we survey things in succession, and our acts of synthesis and our realization of fact are only occasional. This is the tenure of all our possessions; we are not uninterruptedly conscious of ourselves, our physical environment, our ruling passions, or our deepest conviction. What wonder, then, that we are not constantly conscious of that perfection which is the implicit ideal of all our preferences and desires? We view it only in parts, as passion or perception successively directs our attention to its various elements. Some of us never try to conceive it in its totality. Yet our whole life is an act of worship to this unknown divinity; every heartfelt prayer is offered before one or another of its images.
