Years ago a friend of Fr. PR's was in UL Speed Engineering School; the guy was a Protestant, and took instruction and ended up converting to Catholicism. This guy brought up the theory of "Black Holes" with me, postulating that matter is sucked into these Black Holes and consequently destroyed. I wrote him a small refutation stating that sound philosophy is, "Matter can undergo change, but can never be destroyed." Insofar as matter exists, it is good, and good can never be destroyed; and that evil in the philosophical sense, is a privation. A one-winged bird suffers the privation of a wing, and this is evil, in the sense it is a consequence of evil, lacking something due to its nature. This was the short of it. There were multiple issues with his philosophic principles which he failed to see.
The guy took a job with Ratheon down in Texas and eventually lost the faith. It is apparent, and experience has proven time and again, that many people enter the godless universities, and without having solid philosophical principles, their thoughts become corrupted, and they abandon the Faith. But in the end this man left the Faith because of the flesh, and, as any informed Catholic knows, people almost never leave the Faith because of some intellectual aberration.
