Here is my opinion on the subject. I believe that most people, if not everyone, forms beliefs about life as they resolve in their minds two mental processes which many times come into conflict. One force is the intellectual force, human reasoning, rationalization, education by the society around them, logic, and what seems to make sense. The other force is more emotional; it is feelings, hopes, dreams, gut feelings, promptings of the spirit, love, longings of the heart. As you can see these two processes are in themselves complicated and involve many factors. I believe that an atheist has either never been taught to believe in God, or has come to disbelieve in God through the resolution of the processes in his mind. He looks at the facts, and for him it is more intellectually satisfying to reason that God is not necessary as an explanation for what he knows about life. Then there is the emotional factor. There has often been something emotional in his life that turns him away from God. Perhaps he becomes offended when it appears that God is not listening to him. Perhaps he feels that if there is a God then God does not care about him. His study of history, coupled with his reasoning function, leads him to believe that God could not exist as a loving, kind Being and be responsible for all the evil and bad that happens. This is usually due to a misunderstanding of the true nature of God. But in a sense he turns to disbelief as a sort of irrational punishment of God. With that somewhat vague background I would say that in the case of moral absolutes the emotional process--what his heart tells him--decides what he believes. He feels in his heart that there ought to be moral absolutes. His intellectual process tells him that he is smart enought to decide absolutely what is best for mankind. While this may not be entirely consistent and rational, as we see it, there are some deeply held beliefs, wishes, and longings for goodness and certainty that find expression in his unexamined confidence that some things are just that way, and any fool ought to be able to see it as well.

Answer 4

Get 100ml of methanol and add 43ml of water.

Total 143ml.
143 x 0.7 (or 70%) = 100.1 - which in my book is as near as required, as you won't be able to add exactly 43ml of water anyway.

Answer 5

you pour it down the drain and then take a bath in your septic tank.
