I think one reason is that philosophers are more insecure to speak accessibly because non-philosophers are skeptical that philosophers have any special expertise. After all, all people - not just philosophers - have attitudes and points of view on various philosophical questions, and they rather resent being told that there are professionals who can think about these things better.
Rebecca GoldsteinI like that there are so many different ways of looking at the world and I like all of the particular narratives. In any case we will never all see the same way on these [religious] issues. It's the way liberals and conservatives will never see the same way on individuals whereas it’s different orientations and they go too deep down and when we're dealing with questions that can't be definitively answered by science that's where you're sort of... your orientation swells in to fill up the gaps and so we're never always going to agree.
Rebecca GoldsteinOne of the peculiar features of philosophical questions is how eager people are to offer solutions that miss the point of the questions. Sometimes these failed solutions are scientific, and sometimes they are religious, and sometimes they are based on what is called plain common sense.
Rebecca GoldsteinDoes God have a reason for wanting us to be charitable, to take care of those who can't take care of themselves? Either God does or God doesn't, it's just logic. If God has a reason then there is a reason independent of God and whatever God's reason is we should figure it out for ourselves. There is a reason and God doesn't really ground morality at all. God wants us to give charity because it's the right thing to do.
