I would like to study the impact of entertainment and marketing on people. How would studying philosophy help me to that end? Are there particular types of philosophy courses that would help? Particular philosophers?

Beneficent person (-A-) brings two people (-B- and -C-) together for the sake of helping each of them. Years later, -A- discovers that -B- caused harm to -C- at the time when -A- initiated the help. Does -A- have any responsibility for -C-'s being harmed?

If someone has already been mistakenly punished for a crime they have not committed, are they then allowed to go and commit that crime (without punishment)? For example, supposing person A is charged with the murder of B but wrongly so as B was still alive. Does A then have the right, once he's finished his sentence in jail, to go and kill B? He has already been punished for it so you can't punish him twice for the same act!!

If it turned out that colours had four dimensions instead of the perceived three, would that mean that colours we see now do not exist?

Philosophy begins as a search for what constitutes a, or the, "good life". Does that concept have any meaning today and if it does (as I believe it does), why are professional philosophers (I am not a philosopher) more competent to answer it than any layperson who ponders the question? Pablo Santiago de Chile

Is it ethical to stay in a marriage after love is dead?

In terms of the meaning of life, I look at how humanity has managed to claw itself up from hitting each other with rocks to a fairly impressive level of civilisation. Since there is no discernible point to Mankind, perhaps just a furthering of humanity should be the aim? I try to base my morals on this ideal, as well as relying on empathy. Does the panel think that this is a reliable base for morality?

If I am an alcoholic do I have a duty not to have children? What if I have a pretty strong history of being verbally abusive? What if I know I carry Tay-Sachs? You see where I am going here; should there be some criteria under which I am morally obliged not to have children in light of the initial conditions under which they would be living?
