It’s the feast day of Thomas Aquinas’ mentor: Albert the Great, the patron saint of scientists.
I flipped through GKC's Saint Thomas Aquinas: The Dumb Ox, looking for a passage about St. Albert, but didn't find much. I'm sure there's good stuff in there, but my version has no index and I've underlined it so heavily that scarcely nothing stands out. GKC mentioned that STA "constantly" referred back to "the authorities: from St. Augustine to St. Anselm, and from St. Anselm to St. Albert."
Of course, STA didn't refer to Saint Albert, since Albert outlived Thomas by six years.
