There are, indeed, philosophical issues that go with your question. But I think it's important to address the factual background. The premise of your question is that if someone has autism, she can't, as we say, feel other people's pain, or joy, or... And both from knowing people on the autism spectrum and having read around on the topic, I would say that you're mistaken about that. This link https://www.psychologytoday.com/us/blog/women-autism-spectrum-disorder/202006/can-i-have-empathy-if-i-am-autistic isn't to a scholarly piece, but my sense is that it gets things broadly right. The author is a therapist, and also is on the autism spectrum. Her point is that we need to distinguish between feeling other people's emotions and processing/making sense of cognitively of the incoming information that triggers the feelings. The author puts it in terms of a "time lag": for a person with autism, interpreting cues and making sense of other people's behavior may take longer. But that doesn't mean that people...

Suppose I make a promise to you. Then I've taken on a commitment. If I promise to drive you to the airport at 2:00 tomorrow, then I'm not free to do something else at 2:00 tomorrow. That is, I'm not free if I take my promise seriously. Of course, in another sense I'm free as a bird: I could just break my promise. Insofar as I'm not free, it's because I've bound myself, so to speak. But unless you've extracted the promise under duress, I took on the commitment freely, and taking on and keeping commitments is one of the ways we exercise and demonstrate our freedom. There's not just one thing we mean when we say someone is free. If you're locked up, you're not free to leave for external reasons. If you don't have certain capacities, then for internal reasons, you're not free to do things that call for them. (In that sense, I'm not free to sing the high F in the Queen of the Night's aria from the Magic Flute.) And then there's not being free because of restrictions you impose on yourself by choice. But...

It depends on what you mean. I'd be mistaken if I thought that members of my family were more valuable or worthy than other people just because they're my family. In the general scheme of things, my children's well-being is not a bit more important than the well-being of anyone else's children. The same goes, of course, for parents, siblings, spouses, lovers, friends, fellow citizens. But I have a feeling that's not the question you're asking. Im guessing you're asking whether it's okay to treat one's own family, friends, etc. preferentially. In some cases the answer is no. Suppose I'm in charge of hiring a new employee. It would be wrong to hire my daughter instead of another candidate simply because she's my daughter. That would be giving my daughter an unfair advantage. The right thing to do, if at all possible, would be to turn the decision over to someone who doesn't have a personal stake in the outcome. On the other hand, to use a sort of example well-known among philosophers, if I have to...

To get to the conclusion first, I think that the answer is yes, broadly speaking. But I'd like to add a few qualifications. The first is that I'm not sure the root question is about whether it would be ethically right or wrong. It's more like: would it be some kind of confusion to love this sort of machine in this way? Suppose a child thinks that fancy stuffed animal really has feelings and thoughts, but in fact that's not true at all. The toy seems superficially to have emotions and a mind, but it's really a matter of a few simple preprogrammed, responses of a highly mechanical kind. This might produce strong feelings in the child—feelings that seem like her love for her parents or her siblings or her friends. But (so we're imagining) the feelings are based on a mistake: the toy is just a toy. On the other hand, if an artificial device (let's call it an android) actually has thoughts and feelings and is able to express them and to respond to what people like us feel or think, then it's hard to see...

There are several issues here. Let's see if we can disentangle them a bit. First, "beauty is only skin deep." I take that to be a way of reminding us that physical beauty isn't the only thing we care about in our romantic relationships. And it isn't. If the most beautiful person in the world is also the meanest most miserable person in the world, that makes for poor romantic prospects. It's possible to dislike someone intensely and know that they're beautiful, and that's compatible with physical beauty being objective. It doesn't make any problems for aesthetic judgment. That said, it's possible to think that some things or people really are more beautiful than others without thinking that for any two people or things, either one is more beautiful that the other or else they're equally beautiful. There may be things or people whose beauty can't be fully compared. One result may be that you don't find beautiful some things that I find beautiful, and there's no question of one of us being wrong . ...

It's hard to see why it would be morally wrong. No doubt it would upset a few people for a while, but it's not clear that they'd be entitled to be upset. Beyond that. it's not clear what else might make it wrong. If both families are mortally opposed, then I suppose someone might say that one's obligation to one's family demands that you stay "just friends." But it's not obvious that we owe that sort of deference to our families' wishes, and it's certainly not obvious that our family members are entitled to make such demands on us. Of course, I don't know the details of the story. Perhaps if I did, things would look different. But this brings me to what is the actual philosophical issue here. You say that you want the matter settled by reference to some "objective moral standard." But this makes me wonder: are you looking for some sort of derivation of the right answer from a maxim or two? There's not much reason to believe that moral wisdom works that way. The right thing to do is usually a matter of...

Let's stipulate: adultery isn't always immoral. You're pitching the idea that it's usually not immoral ("mostly moral," as you put it.) Your argument, however, doesn't seem to me to be strong enough for that conclusion. Start with something obvious: when people get married, they make promises to one another. Typically, one of those promises is a promise of faithfulness. Not all promises are binding in all circumstances, but in general promise-breaking isn't morally trivial. And encouraging people to break promises isn't trivial either. But set that aside. Let's suppose that adultery is the result of a biological urge, as you say. Since morality often calls for us not to act on our urges, that doesn't tell us much. Your legal/sociological analysis strikes me as a bit thin, but I'm more worried about this: "Making it with a married woman can be very thrilling and the same woman would not be equally exciting if she were single; the supposedly unavailable is always more desirable than the easily...

I'd say most of what you're asking isn't something that philosophers have any special insight into—at least if "important" means "most likely to make for success." When it comes to questions about how daily life actually works, philosophers are in the same boat as everyone else. I suppose someone might say that we can make a distinction between what's likely to work best and what's most important in some not-merely-practical sense. Philosophers might then have something to say, but I find it hard to image that there'd be a single compelling answer. Your last question, however, did pique my curiosity: could there be a romantic relationship without sex or affection? That's a conceptual matter, and is therefore the sort of thing that spins philosophers' wheels. A romantic relationship without sex is clearly possible. Couples who are "saving themselves for marriage" provide lots of examples. And it might be that many people would call an ongoing sexual relationship a romantic relationship even if...

On the one hand, there are no doubt good reasons for incest taboos. For one thing, family life might become hopelessly complicated if sexual liaisons between first-degree relatives were common. To that we can add that when close relatives have children, the risk that their child will have birth defects goes up, and to that we can add further that if such situations became common, there might be unfortunate effects on the genetic variability of the larger population. That said, your first cousin is not a first-degree relative. Furthermore, the fact that a practice would be problematic if everyone engaged in it doesn't mean that it's automatically wrong. After all, if everyone were to practice celibacy, the human race would die out. But even if you think that would be a bad thing, you presumably don't think it means that no one should decide to be celibate. More relevantly: while it's true that when first cousins have children the risks of birth defects increase somewhat, the increase is on a par with...

Let's start with a distinction between your feelings and your actions. I might be flattered that someone is in love with me; the feeling isn't wrong by itself. But if I lead the person on when I don't feel the same way about them, that's another matter. So the question is: are you taking advantage of him? There are a couple of obvious things to ask. If the tables were turned, how would you feel about what was going on? And as things actually stand, how do you think he'd react if he found out how you really feel? That second question is the really important one. If you suspect he'd be unhappy that you're accepting his gifts and attentions even though you don't love him and love someone else, then it's pretty obvious: you're using him as a means to your own ends. That's wrong. Of course there's another possibility: the fact that you enjoy not just his gifts but also his attention and care could mean that there's a difference between the way you say you feel about him (even to yourself)...
