In Pursuit of the Uncaused Causer

Although I have taken the minimalist approach to my online Philosophy course, which ends this week, eschewing the joys of the online, worldwide forums (!!!!!) I have enjoyed pushing or dragging my brain in new directions. Today I continued wrestling with time travel and metaphysics, including the following:

"....we can pursue the chain of causes literally infinitely.... and never arrive at an 'unmoved mover 'or 'uncaused causer' so again the occurrence of the whole chain is without explanation

The resulting blip is a reflection of my current brain-state!
