Conceptually, in the term "species-essence", the word "species" describes the intrinsic human mental essence that is characterized by a "plurality of interests" and "psychological dynamism," whereby every individual has the desire and the tendency to engage in the many activities that promote mutual human survival and psychological well-being, by means of emotional connections with other people, with society. The psychic value of a human consists in being able to conceive (think) of the ends of their actions as purposeful ideas, which are distinct from the actions required to realize a given idea. That is, humans are able to objectify their intentions by means of an idea of themselves as "the subject" and an idea of the thing that they produce, "the object." Conversely, unlike a human being an animal does not objectify itself as "the subject" nor its products as ideas, "the object," because an animal engages in directly self-sustaining actions that have neither a future intention, nor a conscious intention. Whereas a person's "Gattungswesen" does not exist independently of specific, historically conditioned activities, the essential nature of a human being is actualized when an individual—within their given historical circumstance—is free to subordinate their will to the internal demands they have imposed upon themselves by their imagination and not the external demands imposed upon individuals by other people.
