Tauriq Moosa in Big Think:
In my time teaching students about making choices, especially moral ones, based on sound reasoning and evidence, we often range into areas many have not thoroughly considered. After all, everything deserves scrutiny if we are to be fairly sure an idea (or belief) is worth pursuing, defending and so on. If this idea is worth our support, it will pass tests of reasonable scrutiny; if it does not, it either means we must strengthen the idea by addressing its failings or discard it altogether. For example, there is no good reason to justify the oppression of gay people or women – though there are plenty of reasons people do. Thus because there are no good arguments to support oppressing gay people, the idea should be discarded and indeed opposed where it arises. In an effort to battle bad ideas, we should scrutinise (or at least be willing to scrutinise) every view, belief and idea we have.
Nothing is sacred in my class (indeed, we’ve debated the merits of sanctity itself). We engage with questions that focus on real-life matters, which tend to evoke knee-jerk reactions of dismissal and/or disgust.
With this in mind, my students asked whether incest or necrophilia is wrong. Since in many countries, both of these are automatically crimes, I think it’s important to consider what arguments there are for considering these as automatically wrong. However, just because something is right or wrong does not mean that the law follows suit. Something can be legal and be wrong by a moral standard, and vice versa. Here we are mainly considering the morality of these two supposedly taboo types of sexual conduct. Are they, by definition, wrong?
Tariq also looks at whether necrophilia is wrong.
