Has anyone written on the impact (or lack of it) of Descartes on Islamic thought?

Are 18 year olds capable of consenting to be in pornographic productions?

A lecturer I met a few weeks ago said to me (among other things) that up to this point no-one has managed to disprove Kant's famous claim that 'we should always treat others as ends in themselves and never as mere means'. While I agree that this is a noble maxim by which to live our lives, is it true that it has not been disproved? It seems slightly hasty to claim this about anything.

When I look at the room I'm sitting in, I am consciously aware of it as existing outside my body and head. So, for example, I can walk towards the opposite wall and I appear to get closer to it until I reach out and touch it. Now I understand that light is being reflected off a wall, travelling across a room, entering my eyes and this process creates nervous impulses. (In fact a physics would correctly point out that the photons that hit my retina are not even the same as the photons 'reflected' by any object). I understand that these impulses are processed in various parts of my brain, some unconsciously but eventually a mental "schema" representing the room is created. I also understand that there are other processes going on in my brain that create my awareness of different types of "self"s, that continually shift my awareness and that attempt to always produce a self-consistent view of myself and the world. However, my question is not about these (well not directly!). My question is simply how does...

Is it wrong to fall in love and have a relationship with your first cousin even if you did not grow up together and met as adults? There are many taboos about this kind of relationships and some cultures see it as a very bad thing and others don't. I am very curious to know what philosophers have to say about this.

Is there a difference between blind faith and faith? Doesn't faith in a certain sense have to be blind to rational.

Was wittgenstein an atheist?

If I do something, is it fair to say that I am also _choosing_ not to do one of an infinite number of other things that I am not considering at the time of the choice? For example, if I ask somebody "What's your name?", is it accurate to say I am choosing not to ask them "Where are my walnuts?", even if the second question never even occurred to me?

Are 3 and √9 the same mathematical object (in light of the fact that they have the same numerical value), or are they distinct mathematical objects? In other words, are the expressions '3' and '√9' co-referential names (both referring to the number 3), or do they refer to different objects?

During a discussion with a friend about God, a thought I found puzzling but provocative came to mind. I have discussed it with friends, and most seem to think it is contradictory. The thought was more of an argument, and it goes soemthing like this: if it is true that God in some sense is the greatest being that can be conceived, it seems to follow that God is somehow the maximum of all things (e.g. if goodness exists, God is maximum goodness). If this is true then God possesses all qualities; and if God possesses all qualities, it also seems to follow that all beliefs about God, even if they are contradictory, are true (e.g. God is a aupernatural being, God is a natural being). Put perhaps in simpler terms: if God is in some sense all things, then all beliefs about God, even those that contradict each other, are true. Is this even remotely anything that theologians/philosophers have ever discussed?
