According to Duns Scotus, being itself possesses a sort of univocity, or oneness.  This univocity allows the simplicity of life to be quantified into the physical moving via the influence of unseen forces beyond physical control.  

Aristotle's thunderous first sentence is the key to it all "..humans by nature desire to know..."  Today's discussion centers around the meta behind metaphysics, in addition to metaphysics itself: why do humans consider things behind the physical observances; what is it that humans desire to know and how does one arrive to a conclusion in this regard?  What is the meaning of the phrase "that for the sake of which?"  Is it provable that the starting points of things were more than material in the beginning, and therefore contained essence?  Between these questions, is there a reason to be found for why there are no metaphysics departments at our universities?

The perceptual capacity of animals and humans differ in the endless search for the source, the answer to questions.   Is any of this clawing at the heaven's truly helpful?  Aristotle describes his craft as the science of starting points and causes, but how is this an exercise fruitful to the human person?

Such is the discussion today, along with much more.
