List of paradoxes

This list includes well known paradoxes, grouped thematically.

This list collects only scenarios that have been called a paradox by at least one source and have their own article in this encyclopedia.

These paradoxes may be due to fallacious reasoning (falsidical), or an unintuitive solution (veridical).

However, some of these paradoxes qualify to fit into the mainstream viewpoint of a paradox, which is a self-contradictory result gained even while properly applying accepted ways of reasoning.

These paradoxes, often called antinomy, point out genuine problems in our understanding of the ideas of truth and description.
