Let us accept - for the sake of the argument - the unproven assumption that many kids could even get SBE disease out there in the Social Darwinists' belovedly savage "Nature" that existed before Christian compassion peed on their picnic.
Then, yes, the SBEs' premature death out there in early Nature does seem assured - even 'invariable'.
A clear case of what philosophic reductionists (such as Adolf Hitler) liked to call "upward causation", mandated from the virile little bacteria at the bottom to the big - damaged - heart valves at the top.
Seemingly, end of story.
But remember, even when the evolutionary upward causation of tiny mutating genes throw ups three headed horses, the varying reproductive odds out there in the big eternal environment also get to have their say.
And to date, those reproductive odds has shown a decided preference for horses with only one head.
A clear example of Evolution's "downward causation" (from the top big to the bottom small) having its two cent say on the final results.
In September 1940, the upward causation of Aaron (Leroy) Alston's inevitably death from SBE (subacute bacterial endocarditis - the disease that made Rheumatic Fever the number one killer of kids for 50 years) hit a speed bump.
Inspired by Alston's black activist spunk, a middle aged doctor (Martin Henry Dawson) decided to strike his own personal blow for freedom during WWII by trying to stop Social Darwinists in America from doing to SBE patients what Hitler was already doing to their counterparts in Germany under the Aktion T4 program.
Despite Dawson's best efforts with his historic home-brewed antibiotic injections, Alston did not survive in the end, but Dawson's efforts ultimately ensured that ten billion of us - so far - have led longer happier healthier years.
Seventy five years later, the downward causation of Dawson's agape penicillin is still working itself out in all its complex manifestations, all over our world.
Try and reduce that .....
