The secondary Imagination I consider as an echo of the former, co-existing with the conscious will, yet still as identical with the primary in the kind of its agency, and differing only in degree, and in the mode of its operation. It dissolves, diffuses, dissipates, in order to recreate: or where this process is rendered impossible, yet still at all events it struggles to idealize and to unify. It is essentially vital, even as all objects (as objects) are essentially fixed and dead.
It seems to be the special peculiarity of human beings that they reflect: they think about thinking and know that they know. This, like other feedback systems, may lead to vicious circles and confusions if improperly managed, but self-awareness makes human experience resonant. It imparts that simultaneous "echo" to all that we think and feel as the box of a violin reverberates with the sound of the strings. It gives depth and volume to what would otherwise be shallow and flat.
I am not engaged to Christianity by decent forms, or saving ordinances; it is not usage, it is not what I do not understand, that binds me to it -- let these be the sandy foundations of falsehoods. What I revere and obey in it is its reality, its boundless charity, its deep interior life, the rest it gives to my mind, the echo it returns to my thoughts, the perfect accord it makes with my reason through all its representation of God and His Providence; and the persuasion and courage that come out thence to lead me upward and onward.
A dissolute character is more dissolute in thought than in deed. And the same is true of violence. Our violence in word and deed is but a feeble echo of the surging violence of thought in us.
