Abstract

In Heraclitus’ time, thymos and psyche carried highly similar or even identical meanings, because both could refer to life, courage, personality, emotions, and reason. Heraclitus probably worked with all of these meanings. He may have been partly inspired by Homer and post-Homeric literature, where the two terms were likewise placed side by side and often used interchangeably. In Heraclitus, thymos and psyche are not opposites in terms of signification. Oftentimes, they can be “swapped,” and their meaning and “costs” exchanged. The source and cause of this special exchange is desiring or wanting (thelein), which connects all these senses but is also the source of conflict and fighting. Desire—regardless of what it is and what is desired—is simultaneously the acquisition of the desired object or person and a way of paying for it. This struggle for the desired object is difficult not only because of its consequences (the price), but also because it is not possible to permanently stop desiring, which is why this struggle cannot be brought to an end.
