On AbortionIt's an interesting problem. At what point does a fertilized egg, the most basic state of a creature that can one day turn into a human, attain the intrinsic value that we associate with human life? Do we base meaning upon potential, or do we base it upon actuality?
If we find meaning in potential, then we encounter a conundrum: at what point is potential established? When we have brain activity? When we have a hearbeat? When we have a mass of cells the size of a peanut? A flea? A pair of cells? A single fertilized egg? Should each egg in the female be treated as an irreplaceable entity?
The latter is an interesting point to consider, largely because it's true, and presents a argument to the point of absurdity with regards to the idea that humanity is based on potential. Women don't get more eggs, which means that each one represents a unique person. If the woman does not become impregnated during her cycle, that egg is wasted. That person is wasted so that it never comes to be. A living, breathing human, capability of expression, laughter, and life, is sacrificed every monthish that a woman of reproductive age chooses to not become pregnant. Because of the conscious action of one human, another will never experience a sunset, or friendship, or a loved one's touch.
Now, clearly, it would be utterly ridiculous if we were to actually be terribly upset about that. That sounds really callous after I just spent a paragraph building it up, but it's the truth. We persecute murderers for the murder they committed, not the potentially cataclysmic actions they may have instigated by exterminating the gene-line of random Joe. Eggs aren't people. Sperm aren't people. Fertilized eggs aren't people. The point at which we decide that a bundle of cells is a human life with inherent value is arbitrary- whether that be conception, first, second, third trimester or crowning.
A further point to consider is how bizarrely this looks, objectively, from the purpose of preserving human life. We worry, debate, and dither constantly over whether or not the process of abortion constitutes murder and when does it cross the line. However, the average cost of a vaginal birth is a bit less than 10k, and the yearly cost of a child is a bit more than 10k after that, with steepening penalties. Google tells me that the total cost is somewhere around 230k. An abortion, depending on the time implemented, costs between 0.5k and 3.5k. Now, GiveWell is a well known charity feeder which takes in money and distributes it to charities that work well. The charities they use (

So, if we assume that abortion sets at lives 0, we can still score 4 lives for the money we save raising the child to end up with a net life total of +4, as opposed to a standard +1 or +2.
Now, this isn't a justification for why you should never have children. Subjectively, if this was my baby, I'd probably fuck someone up if they tried to tell me that my infant wasn't cost effective. However, when your argument boils down to 'You're committing murder', you're really letting a lot more people die than you're saving. Personal opinion, it's a lot better to take care of the people who are already in this world and dying than to force an mother to take care of a child she doesn't want and potentially tank her quality of life in the process.
Ooh... Eugenics is a fun topic too. I'll put my two cents in there later.
