Cotton Mather, the colonial-era New England Puritan, wrote:
I was once emptying the Cistern of Nature, and making Water at the Wall. At the same Time, there came a Dog, who did so too, before me. Thought I; “What mean and vile Things are the Children of Men, in this mortal State! How much do our natural Necessities abase us and place us in some regard, on the Level with the very Dogs!” … Accordingly, I resolved, that it should be my ordinary Practice, whenever I step to answer the one or other Necessity of Nature, to make it an Opportunity of shaping in my Mind some noble, divine Thought.
Takeaway? For starters, Calvin needs to take his urination ruminations to a higher spiritual plane.
