 It is by means of Empfindung or sense experience that sentient beings are able to distinguish individuals from one another, including, in some instances, individuals that share the same essence. The form of experience is temporality, which is to say that whatever is directly experienced occurs “now”, or at the moment in time to which we refer as “the present”. Experience, in other words, is essentially fleeting and transitory, and its contents are incommunicable. What we experience are the perceivable features of individual objects. It is through the act of thinking that we are able to identify those features through the possession of which different individuals belong to the same species, with the other members of which they share these essential features in common.
