A little more analysis on top of what I said in regards to the broken window fallacy.
His first argument is a contradiction. If you are told that you should do something because it’s in your own interest then you are NOT being advised to be altruistic.
He doesn't define altruism. Ayn Rand wasn’t criticizing benevolence and good will when she argued against altruism. In fact, she felt her morality of self-interest provided the foundation for both of these things.
Now, for instance, lets say someone is in need, so much need that they require someone to care for them for all their life. You don’t want to do this, and you know it won’t be good for you, but according to altruism, you should. How does this benefit you in the long run? Why does society matter in this situation? Why do your genes matter at this point?
Finally, the argument that the main goal of life is to reproduce. That’s all. No ifs, ands, or buts. Yes, it’s that true that for praying mantis, the purpose of life is to reproduce. The male is eaten while he inseminates his mate, so that she can have enough energy to lay her eggs. The male allows this happen because his sole purpose is to pass on his genes.
How does that apply to humans? While some of us are equipped to reproduce, it doesn’t mean that reproduction is our ‘ultimate evolutionary goal’. In fact, there is no such thing as an ‘ultimate evolutionary goal’, because evolution has no goals. Evolution is not a planned process. It does no engineering. The end products were never visualized. No goals exist. There is no thought of failure or success. There is no seeking of perfection. There is no seeking of anything. Evolution does not do anything. It only happens. As animals we are sexual beings, but that doesn’t mean we only have sex for the purpose of reproduction. This is really easy to prove: people who are infertile have sex, get married, etc; couples who are fertile may also choose not to have children for a variety of reasons.. yet they are still a ‘couple’ and they still have sex. So there are other reasons why individuals unite and have sexual relationships, besides reproduction. If you don’t believe it, try to go up to the first woman you see and ask her if she’ll have sex with you. If reproduction is her ultimate goal, she’ll say yes. (That’s what a preying mantis would do, right, so why wouldn’t a human?)
Just to add a little more.
Consider the first sentence, “You should be altruistic because in the long run, it will be beneficial not only to society, but also to yourself.” Altruism, by definition, is sacrificing one’s self for the sake of others. This is antithetical to the furtherance of the self and in no way could “be beneficial.” I think you’re confusing kindness with altruism, so I’ll point out that kindness and good will towards others are conditional acts, filtered by the virtue of justice. We treat those we judge to be valuable with kindness. An argument could be made that other people in a society are valuable as partners in trade, and thus could reasonably be treated kindly.
Take a look at the next sentence, “Being altruistic fosters and encourages a society in which people help those in need of help, which ultimately means you will be helped when you need it.” To which I would reply, “Says who?” Altruism does not guarantee that you will be helped. Altruism is simply a moral philosophy telling individuals what they ought to do. You’re extrapolating a moral philosophy into probabilities that, in reality, contain far more variables than you’re willing to admit. Furthermore, history has shown altruism to give birth to the most heinous dictatorships (Soviet Russia, Hitler’s Germany) and justify the most deadly actions (the mass slaughter of Jews in the 20th century in the name of preserving the greater society). Far from providing ‘eventual help,’ altruism is much more likely to kill you.
The major problem with confronting what he wrote with logic is that he is speaking in large-scale terms, i.e. “society.” Why should we be moral? What constitutes a moral action? What constitutes a value? These are all questions that must necessarily begin at the individual level, but the paragraph also mixes concepts and drops contexts which than continues to be built upon assumptions, stretched from nothing, and applied broadly to a society.
Here is the bottom line: altruism is always the sacrificing of the self to others; of higher values for lower values, and in no possible way is that ever beneficial to an individual or a group of individuals because it necessarily truncates values, lives, goals, and minds. No amount of twisted logic could sanction such an anti-individual, anti-life philosophy. And remember, morality is a code of ethics to guide the actions of individuals. “Society” is nothing except for a collection of individual human beings.
