Bar wisdom can also be Vulcan logic

In Spider Robinson's Callahan series (1977+), we are often referred to "Callahan's Law" of  "Shared pain is lessened; shared joy, increased"
Ever since I came across that wisdom, I have tried to use it to help myself and others travel the challenges of life.  It was therefor a great pleasure to see Callahan's Law expressed as Vulcan logic. I wonder how many others have caught this logical evolution of the concept.

"It is true that logic is often its own reward -- but it is a reward best shared with others. That which is beautiful is magnified by being shared with others. That which is painful is often moderated by being shared. Both approaches are equally logical"
