I have been duscussing lately with my friend about thinking. We both agree on what thinking can lead to. But, we disagree on wether or not you should think. Our theory is that thinking will often/most cases lead to unhappiness or depression because most question/problems are for the most part hard to solve. For example, what is the meaning of life? Not an easy question to answer, and the answer you do get may be sad. Therefore, I think not thinking will be good for a person so hin won't get to a stage where hin gets sad. However, my friend see this as fake happiness because you only hide sadness away instead of dealing with the problems. The problems are philosophical and not physical or physiological. So the question is, should people asks "why" questions more often and seek answers to find true happiness? Or is not thinking at all about philosophically questions just fine?

I belong firmly to the camp that advocates more thinking rather than less, especially when the issue is philosophical. Take your sample question: What is the meaning of life? I would answer it this way: In the sense in which the question is probably intended, there isn't and couldn't possibly be any such thing as the meaning of life. (See this link for details.)

Should that answer make someone sad? I don't think so. When we come to see that the notion of the meaning (i.e., ultimate purpose) of life makes no sense, we can recognize that seeking the meaning of life is a logically misguided quest, like seeking the largest integer. I hope no one feels sad that there's no largest integer.

Really it's an empirical question whether thinking about philosophical issues makes people, in general, happier or sadder than they would otherwise be. I don't know the answer to that question, but in my own case I believe that philosophical thinking has greatly contributed to my overall contentment. But even if it hasn't, that wouldn't settle the philosophical question of whether I ought to engage in philosophical thinking or not. For John Stuart Mill may well be right that it's "better to be Socrates dissatisfied than a fool satisfied," by which I take it he means that philosophical reflection needn't provide contentment in order to be valuable.
