Variant: We look not at the things which are what you would call seen, but at the things which are not seen. For the things which are seen are temporal. But the things which are not seen are eternal.

Works, VII, 17.
Context: The great thing however is, in the show of the temporal and the transient to recognize the substance which is immanent and the eternal which is present. For the work of Reason (which is synonymous with the Idea) when considered in its own actuality, is to simultaneously enter external existence and emerge with an infinite wealth of forms, phenomena and phases — a multiplicity that envelops its essential rational kernel with a motley outer rind with which our ordinary consciousness is earliest at home. It is this rind that the Concept must penetrate before Reason can find its own inward pulse and feel it still beating even in the outward phases. But this infinite variety of circumstances which is formed in this element of externality by the light of the rational essence shining in it — all this infinite material, with its regulatory laws — is not the object of philosophy.... To comprehend what is, is the task of philosophy: and what is is Reason.
“What unseen pen etched eternal things
on the hearts of human kind
but never let them in our minds?”

Notes from Devotional Authors of the Middle Ages (1873-1874)
Context: Mysticism: to dwell on the unseen, to withdraw ourselves from the things of sense into communion with God — to endeavour to partake of the Divine nature; that is, of Holiness. When we ask ourselves only what is right, or what is the will of God (the same question), then we may truly be said to live in His light.
