The Gattungswesen (species-essence), human nature of individuals is not discrete (separate and apart) from their activity as a worker; as such, species-essence also comprises all of innate human potential as a person. 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.
