Quotes About Counterfactually

A good general strategy is reasoning counterfactually: if someone tells you that X is true, ask yourself—(i) what would they say if X really is true, and (ii) what would they say if X is false? If the answer to (i) and (ii) is "they will say roughly what they just said now," then their words provided you with exactly zero information. In general, know when it's really important not to take people's words at 100 percent face value.
