Theoria is an academic journal focused on theoretical, historical, and fundamental research in science. It provides a multidisciplinary exchange platform for scholars, covering a wide range of topics from the various branches of analytical philosophy, such as philosophy of language, philosophy of mind, philosophy of logic, and philosophy of mathematics, to philosophy of science and social studies of science.

The journal is distinguished by its preference for papers in English and Spanish, which reflects its vision to foster dialogue among scholars in diverse cultural and linguistic contexts. By accepting submissions in both languages, it not only facilitates the exchange of English and Spanish-speaking academic circles, but also helps bridge the differences in philosophical and scientific thought between different regions.
