A lie is neither a false proposition, nor a mistake, nor a mere fiction; it is a type of fiction, an act, and precisely an intentional act. An act calls for a subject, and therefore a lie is inseparable from its subject. Together, they make up a real object: it has to be real, since a lie produces effects, and the cause-effect relationship only holds between real beings. Like every real object, a lie unfolds in a (phenomenological) context. But there is more: it identifies a (dialectical) context.
