I was recently thinking about why people do the things they do, and it occurred to me that the reasons are not too many. I could think of the following as possible causes for people to act at all:
- The thought that what they do will give them happiness
- The thought that what they do will give somebody else happiness (this is actually not entirely true, and I'll come back to it in a moment)
- The thought that what they do will give others pain. Sadists you may identify with this ;-) Actually, this also points back to 1 above, because the deeper motive for causing hurt to others is a (wrong) notion that that will give them happiness.
The more I think about it, the more I'm convinced that there can be no more significant reasons than our own happiness that impels us to act in this world; reasons 2 and 3 mentioned above are really only special instances of reason 1.
