It is classical Catholic thinking to speak of emotion, reason and will as separate things.  I am curious what others here think about how to define those 3 terms.  (No regurgitations of the Catechism please, just your own thoughts).  For myself, the boundaries between those reason, emotion and will are murky and I cannot place them in separate silos.  I also believe there are mental and spiritual experiences that don't fit any of these definitions, such as mystical experiences.  Any thoughts, anyone?
