A bag of sand.
If one were to have a bag of sand, say two lbs were of sand granuals; now assume this person removed a thimble full of sand, is it a lot they have removed in comparison to their bag of sand that remains?
Further to the point, if one had a room of people, and they did a similar weeding out process of a person or even two from a room of say two-hundred, would that actually make a difference in the room?
The answer is to be taken I suppose, by how you'd view people, qualitatively one person removed from the poulation could very well change, reshape, or all together transmute the universe in a very negative way, however, quanitatively the population is only effected by a very small percentage.
Now, does natural selection play a part in this weeding out, that is, say person A) we'll call Robby, will become a chemical engineer, and eventually cure Aids. If he were allowed to stay within the population that is, but he is not afforded such luxary, in fact he recently died in a very nasty car crash and had he survived which is slim, and rather improbable idea to achieve anyway, he would never be able to achieve his fated victory over biology, moreover, does nature foresee this great tragedy and allow another the ability, the grace to cure the AIDS anyway, this sounds like a system of entrophy with aids as the deteriorating matter; or is it more a fact that if Robby were removed would man forever be blightened by AIDS?
You tell me..
