I like to know how a philosopher comes to conclusion that a particular thing has an Instrumental value or an Intrinsic value. I read in Wikipedia, in Swedish section, that ice cream has an instrumental value, that there is no end in itself to eat ice cream, but it is good and makes me feel good. Feeling good has an intrinsic value.
Is it a matter of on's preference to arrive at that kind of conclusion? Is it possible to say that any thing that is made by human has an Instrumental value.?
Thank you for your help!
