Fickleness
Leaving others to absorb the cost of commitments abandoned without adequate reason.
Habitually abandoning considered purposes or commitments without an adequate reason.
Imagine this: Two friends have arranged to move a heavy bookcase together. One arrives holding a picnic basket: a new plan has replaced the old one without a conversation.
How the pattern works
A changed preference is not yet a broken commitment. It becomes a problem when the earlier agreement is treated as if it vanished the moment a more attractive idea appeared. The friend still waiting beside the bookcase has planned around a promise that only one person has silently canceled.
Fickleness is the familiar display name here for Inconstancy: abandoning a considered purpose or commitment without adequate reason. The new picnic may be a good idea in itself. Its attractiveness does not answer the separate question of what is owed concerning the arrangement already made.
What it costs a shared life
People who cannot rely on an agreement must make backup plans, reduce what they attempt together or carry work they did not accept alone. The fickle person may enjoy a succession of fresh beginnings while others repeatedly manage unfinished business.
A distinction worth keeping
Changed evidence, illness, a withdrawn consent or an unfair demand can justify changing course. Inconstancy is not a duty to remain in a relationship or complete a harmful plan. Dishonesty may involve a promise never sincerely intended; Inconstancy can abandon one that was genuine when made.
What a useful response can change
Treat the existing commitment as a matter to resolve, not an obstacle to the new enthusiasm. Contact the affected person before assuming the change is harmless.
Explain the reason and consider the practical consequences together. A justified change may still need a handover or another arrangement.
Make fewer promises if necessary. A modest agreement that fits one’s capacity gives others more usable help than a stream of enthusiastic commitments left behind.
Questions for reflection
- Who has already arranged their time around my answer?
- Am I reconsidering for a reason or merely following the newest attraction?
Other perspectives
It is to no purpose that the person who has been guilty of the breach of it, urges that he promised in order to save his life, and that he broke his promise because it was inconsistent with some other respectable duty to keep it.
Adam Smith · The Theory of Moral Sentiments · Read the source
Smith examines a disputed promise made under pressure and a competing duty. The passage introduces reasons a commitment may need reassessment; this reading does not adopt an unconditional rule that every promise must be kept.
But nobler spirits may converse, even in the midst of pleasures, if the mind be well guarded with constancy and resolution.

Bacon connects steadiness with a guarded purpose amid pleasures. Applied to the picnic case, the question is whether a fresh attraction has displaced a considered agreement, not whether enjoyment itself is suspect.
