The Six Basic Pleasures Theory

I don't have time to flesh this out, but I just had a thought that I'd like to explore later.

Theory:

There are six basic paths to pleasure, for a human:

• enjoying a physical experience (e.g., sensory input)
• enjoying a shared experience with someone else (i.e.: laughing at a joke)
• enjoying a sense of accomplishment (for example, "I just jumped 12 feet, I rock!")
• enjoying a sense of recognition (for example, "Dude, you just jumped 12 feet, you rock!")
• enjoying a sense of connection (best example being love)
• enjoying a sense of purpose (be it participation in a project, a sense of nationality, or religious experience.)

 I'm not sure, as I type it out.  But I have to get back to work.
