A person has to care for their children as a “responsibility”?
Responsibilities are chosen; duties are not. It may sound similar, but there is a world of difference.
Responsibility is taking ownership of the consequences of one’s actions. It is respecting the effect that one’s actions have on the rights of other people, as well as what effects those actions will have on oneself.
Duty is devotion to otherworldly commands - either from unseen deities or “just because.” They have no basis in the rights of others or indeed any basis on this earth.
The latter is in fact feeding on and ripping off the former, smuggling in peoples’ sense of value for the former in order to enslave them.
"Just as there are no rights of collections of individuals, so there are no rights of parts of individuals - no rights of arms or of tumors or of any piece of tissue growing within a woman, even if it has the capacity to become in time a human being. A potentiality is not an actuality, and a fertilized ovum, an embryo, or a fetus is not a human being. Rights belong only to man - and men are entities, organisms that are biologically formed and physically seperate from one another. That which lives within the body of another can claim no prerogatives against its host_" (OPAR 357)._
Actually, upon rereading this, it looks like he’s arguing from the stance that things that aren’t fully human don’t have rights.
Stop. Stop right there, because you have correctly understood what he is going for. A lump of tissue is not a human being. Your question was about children , not about mindless lumps of tissue.
I think your second point is stronger, but I have a question about it as well. How can love be a “selfish” emotion when it can lead to self-sacrifice up to and including the loss of one’s life?
Love is a devotion to that which one values. To the things (and people) that make life worth living for you. Sacrifice, as defined by Objectivism is not simply any loss of value, but the loss of a greater value in exchange for a lesser value or no value.
If you love your wife more than your money then it is not a sacrifice to spend all of your money to cure her terminal disease. Love does not in fact lead to self-sacrifice.
Altruists want you to think so, though, because just like with duty, they smuggle in some of what we value to try to sell their poison.
Is this helping you to understand the matter?
