Things I like about Thomism (lacking even the slightest expertise in the philosophy though still, according to some readers, capable of forcing every topic, up to and including the more opaque levels of high finance Capitalism, through the Thomist "grid"):
It takes its name from one of the greatest philosopher-saints (a elite class of rare men indeed) that ever lived.
It is a branch from the very vine of Western philosophy, Natural law, which Christianity shares with the ancients, but which nefarious moderns have schemed to subvert and overthrow in order to substitute their own, narrower doctrine.
It begins at the great affirmation of being which is faith, while so many of its modern usurpers begin with some wild and even crankish posited negation. Let us imagine mankind in his material estate simply; let us look on man as he is without any of the things his poets and prophets have spoken of, or his painters, even those of the most ancient cave, have painted, or his musicians played a song -- let us first imagine man thus, and then begin our study of his politics.
Against this madness Thomism rings like thunder, and ever shall. In a word, Thomism is trustworthy, and modernity is not. I like this too about Thomism.
Readers may add their own; or, if they must, point out the faults in my impulsive sketch.
