I feel pretty confident about philosophy now, and I have developed some conclusions on certain issues. First of all, I don't think that humans are completely free. I believe that human freedom only goes so far as freedom of actions. As for free will, I don't believe humans have it, and if I had a choice I would not want to have free will because then life would be in total chaos. Life would only be controled by chance, causing people to do whatever happens at any moment.
Freedom of action allows humans to do what they want, but only within certain limits.
I don't believe that suffering is absolutely not necessary. I think suffering is necessary, but only to a certain extent. For example the suffering that was going on during the war times, with the many concentration camps, was maybe not that necessary. I believe relative suffering is necessary, but not absolute suffering. The question of who has the right to euthanasia will be a debatable question for years to come yet.
