 In other words, logical thinking is accompanied essentially by a feeling of the thinking subject’s freedom in thinking. But while logical thinking may be accompanied by an especially strong self-awareness of the mind’s own activity, this feeling is not unique to logical thinking, since active apperception more generally is also accompanied by the sense of subjective activity. By contrast, logical evidence and universal validity are characteristics possessed by logical thinking “to a higher degree than by any other psychic function” (L I: 78). By “evidence”, Wundt means the character of compelling necessity accompanying a logical judgment, what we might call self-evidence (L I: 78, 79). A thought (Gedanke) may exhibit immediate certainty, obvious without any mediating thought-acts; or a thought may be mediately certain, grounded in prior thought-acts. Immediate and mediate evidence have their source and foundation in intuition (Anschauung): immediate evidence immediately, mediate evidence mediately (L I: 82–3). Intuition is not identical with evidence, for evidence only
