Always been one of my pet theories. Everything we experience and conceptualize is filtered through our consciousness anyway, so we might as well conceive of the universe as a huge brain. The reality is our physical senses are pretty limited as tools to perceive anything at all, so we might as well swing for the fences with creative ideas.

I am a firm believer that every PhD candidate in the hard sciences should be required to dose on 500 mics of Owsley grade Acid before receiving their credentials, and 250 mic refreshers on their graduation anniversary from then on out. That will keep their mind open and fluid and prevent any calcification due to over education and ego issues. Once you slap a 'Dr.' on the front of someone's name they start drinking their own Kool-Aid.
