Definition: The term "seleucidian" is a concept from Greek mythology that refers to the ability of certain animals, such as dogs and horses, to perceive their own emotions and thoughts. These animals are known for their remarkable ability to recognize the subtle cues in human facial expressions and gestures, which can reveal their true feelings or intentions without any external stimuli.
