To clarify a previous thought.

There two parts to logic. One is the premises you start with. The other is logical deduction via inference. While the first one, the premises you use, may vary, the set of valid logical inferences always remains the same. So John, you’re still illogical. To wit:

  • “Boy I’m full. I think I’ll have some more rice.” Illogical.
  • “I hate it when people are selfish. For example, Mr. X is always kind, generous, and self-sacrificial.” Illogical.
