What is love?

  Desire to incorporate something/someone into yourself?

  Not so bad. I love knowledge. I love understanding. I love NY
  style pizza. I want to incorporate it into myself. In short, I
  "want".

  Is "want" always = to love?

  Well, want also means "lack". If I want, that means I lack.

  I think the word "love" or the concept rather, suffers from a
  lot of simultaneous sets of meaning, all overlapping. One of
  those "words that tries to do too much", I think By
  incorporating into yourself, it doesn't have to mean in a
  "nutritional sense" either. It can also mean incorporating into
  your daily routine - into your Time, which is also a part of
  yourself.

  So do you love your cats? Well, you're willing to incorporate
  them into your daily routine, if you view your "self" as also a
  set of actions that occur over a period of Time.
