While I appreciate that mind should be given room to flow I find searches for provable and explainable things far more fruitful than pure metaphysical constructs. Mainly because we are so good at fooling ourselves and our thought processes are so full of errors that I'm highly skeptical of the "truth" value of any thought process that does not perform stringent reality checks from experimental data or mathematics.

Then again, to find new interesting points of view mind should be given the capability to flow freely - but to actually utilize those fantasies in finding new truths requires also hard labor.
