Franklin observes that people do not always state the true reason for their actions. Instead, they may offer explanations that sound reasonable or respectable while concealing a simpler motive that is less flattering, more personal or more difficult to admit. These “pretended reasons” can be intended to persuade others, but they may also reflect self-deception.

The saying draws attention to the difference between justification and motivation. A person can construct several plausible arguments for a choice without identifying what actually caused them to make it. Franklin’s broader point is that clear judgement requires examining motives as well as stated reasons. This does not mean that every explanation is dishonest or that motives are always hidden deliberately. Rather, it suggests that people should be cautious when reasons appear unusually elaborate and should consider whether a more direct underlying motive better explains the decision.
