Is Happiness the Meaning of Life?

Agnostics are people who are generally undecided on what they believe in. Or at least, they are people who would not say they have committed themselves to one of the major world beliefs. In western culture this indecision seems to result in them inventing their own belief system, but in a vague kind of way.

One of the most common things I hear agnostics say or imply, if they are ever talking about belief, is that life is all about happiness. This may be dressed in phrases like "follow your heart" or "be true to yourself". The core thing that decisions come down to, says this belief, is that I should be happy.

Unfortunately, there are issues with this belief.
