Esistenza

Esistenza (Italian for existence) refers to the state or fact of being real or present. In everyday language it denotes that something is the case, whether a thing that exists in the world or an event that occurs. In philosophy, esistenza is a central concern of ontology, the branch that studies what exists, how beings are categorized, and the conditions of their being.

Etymology: from Latin existentia, from exsistere, meaning to stand forth or come into being.

Philosophical overview: The question of what exists and what it means for something to exist has a long history. Early discussions include Parmenides’ claim that only being is real and Heraclitus’ emphasis on change. Aristotle developed an ontology of substances and categories. In the medieval period, existence was treated in relation to God, creation, and universals. In modern philosophy, Kant argued that existence is not a real predicate that adds content to a concept; Descartes linked existence with thinking. The 19th and 20th centuries brought existentialists such as Sartre and Heidegger, who foregrounded human existence, authenticity, and the sense of being-in-the-world.

Contemporary debates: Realism about universals, the status of abstract objects, and the ontological commitments of scientific theories remain central. In science, existence is often tied to empirical detectability and causal efficacy, while in mathematics existence proofs establish the presence of objects under given axioms. The topic continues to shape how we describe reality and our place within it.
