transparency

The use of reason makes things transparent to the mind. We do not, however, see what is transparent. We see that which is opaque through the transparent-the opaque which was hidden when the transparent was not transparent. We see either the dust on the window or the view beyond the window, but never the window itself. Cleaning off the dust only serves to make the view visible. The reason should be employed only to bring us to the true mysteries, the true undemonstrables, which are reality. The uncomprehended hides the incomprehensible and should on this account be eliminated. (Gravity and Grace, p.132)
