We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
That's a term which has come into fashion lately, and it deserves to. Counterfactuals are a specific variety of BS, as our commenter notes.
The term can be used as a noun or as an adjective. The key to it is its conditionality (If...,then...might have...); the past subjunctive, combined with its lack of factual content. For example, "You bozo - you left a burner on. You could have burned down the house." Well maybe - but it did not happen. Thus no fact.
(An "indicative conditional," by way of contrast, is a past conditional which is founded on a real, factual consequence which occurred. For example, "If you bozos hadn't left the gate open, the dog would not have run into the street." Indicative conditionals are also debatable, due to their speculative nature, ie, cum hoc ergo propter hoc. For example, in my case, almost every time I water the garden, it rains afterewards.)
Counterfactuals are often used (abused) to make emotional arguments. "If the stimulus had been 3 trillion dollars, our unemployment rate would be 4%."
(Philosophy / Logic) expressing what has not happened but could, would, or might under differing conditions
(Philosophy / Logic) a conditional statement in which the first clause is a past tense subjunctive statement expressing something contrary to fact, as in if she had hurried she would have caught the bus.
Umberto Ecco, in Foucault's Pendulum makes the point that the conclusion derived from a counterfactual conditional is always correct precisely because the premise is false. If I were not writing this, I would be ... fill in the blanks.
