# Ontology - **Website:** - **Primary alias:** `ontology.co` ## Description Theory and History of Ontology is an educational philosophy website created by Raul Corazzon and part of the Digital Quadrivium Project, a group of four websites devoted to ontology, logic, rhetoric, and bibliographies in religion and philosophy. The site explores ontology as the theory of objects and their relations, explaining distinctions among types of entities and approaches such as formal, descriptive, and formalized ontology. Its resources cover the history and theory of ontology, the vocabulary of the field, major ontologists, the history of truth, categories, universals, and comparative philosophy. The website also examines ontology’s connections with metaphysics, logic, semantics, and the study of language and reference. Visitors can consult extensive bibliographies, author information, publication abstracts, and selected critical commentary. More than 16,800 bibliographic references are noted across several European languages, with material intended for students, researchers, and readers seeking deeper study. The site offers content for online reading or download as an ebook, along with search across the four Digital Quadrivium websites. ## Industries - 🧪 Science and Education - 🧪 Philosophy _(under Science and Education)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/id4xAfLAt8/w/180/h/180/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1793162947542) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Paradiso | #3b8a8d | accent | | Olive | #668000 | dark | | White | #ffffff | light | ## Fonts - Inter — asset _(google)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
