-- How many
Hegelians
-- does it take to screw in a light bulb?
Two, of course. One stands at one end of the room and argues
that it isn't dark; the other stands across from him and says
that true light is impossible. This dialectic creates a
synthesis when the bulb gets screwed in.
Note: Hegel and Marx use a logical procedure called
dialectics to seek answers to seemingly mutual exclusive
positions. Shortened it is "thesis, antithesis, synthesis".
Thus 'no light' and 'no dark' can arrive at a middle ground
through logical examination 'it's dark but it can be made
light'.
