Logic is as logic does

Seeing the new Star Trek* movie this weekend reminded me of a definition of logic I employ often:

Logic is the set of assumptions you embrace to get the result you want.

I seriously doubt that this is original with me, but I haven't found a source for this beyond myself... so far. I will keep looking.

I also know that scholars of formal logic and reasoned thought may find this unpalatable, but in my experience this is how most people use logic.

More later,
