This was the dies natalis (in the Catholic sense) of philosophy
professor Garth L. Kemerling.
From Kemerling's internet "Philosophy Pages" —
"First, it must be possible in principle to arrange and organize
the chaos of our many individual sensory images by tracing
the connections that hold among them. This Kant called

Second, it must be possible in principle for a single subject
to perform this organization by discovering the connections
among perceived images. This is satisfied by what Kant called
the transcendental unity of apperception."
