Ouch. It hurts. I'm a terminally unmarried man, and probably a "philosophical adolescent" as she puts it: I see a family as a bad thing for health, all these people at my home, or all these obligations to visit relatives who I do not know really and do not care of. And probably because of this I cannot understand what is she talking about. For example, she talks about Descartes wondering do other people exist:
> Now I rather think that nobody who was playing a normal active part among other human beings could regard them like this. But what I am quite sure of is that for anybody living intimately with them as a genuine member of a family … their consciousness would be every bit as certain as his own.
Probably they would be be certain, but why does it matter what they are certain of? They can be mistaken. All these relatives always want something from you, or idk like my parents have a great hopes for my life, which I cannot fulfill and I wouldn't even try, but still they will make me feel guilty about it. Of course in such an environment you cannot think straight, and you have no time to think about some abstract things, you'd prefer practical solution to ignore a question from which follows no practical implications. It is even a rational thing to do, but it doesn't make them right automatically.
So, it seems, that being an unmarried man I'm not qualified enough to understand what is this about. Yeah, it hurts. Luckily she wrote a book about it, probably the book will have a clearer message.
