Question: Drago Đurić taught a branch of philosophy that explores the nature of what?

Context paragraphs:
Philosophy of space and time: Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology, epistemology, and character of space and time.  While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy.  The subject focuses on a number of basic issues, including whether time and space exist independently of the mind, whether they exist independently of one another, what accounts for time's apparently unidirectional flow, whether times other than the present moment exist, and questions about the nature of identity (particularly the nature of identity over time).

Philosophy of mind: Philosophy of mind is a branch of philosophy that studies the nature of the mind.  The mind–body problem is a paradigm issue in philosophy of mind, although other issues are addressed, such as the hard problem of consciousness, and the nature of particular mental states.  Aspects of the mind that are studied include mental events, mental functions, mental properties, consciousness, the ontology of the mind, the nature of thought, and the relationship of the mind to the body.

George N. Schlesinger: George N Schlesinger (Nov 7, 1925 – June 27, 2013) was a philosopher, rabbi, and author.  He made major contributions in the areas of philosophy of religion, and philosophy of science.  He taught and conducted research as a professor of philosophy at the University of North Carolina at Chapel Hill, from 1967 to 1999, and as a visiting professor at several other universities.  His teaching and research interests included philosophy of time, philosophy of logic, and theism.  He authored 10 books and more than 300 articles, earned many awards, and gave many presentations as a sought after speaker... His presentations at a summer conference resulted in the Philosophy of Time Society.  This society is still active to this date.  Schlesinger was also an ordained rabbi, and authored many articles in the area of philosophy of Judaism.  He led services, and taught at the University of North Carolina Hillel, as well as yeshivas and synagogues in England, Australia, and Israel.  As an author, he has been largely collected by libraries worldwide.

Practical philosophy: The division of philosophy into a practical philosophy and a theoretical discipline has its origin in Aristotle's moral philosophy and natural philosophy categories.  In Sweden and Finland courses in theoretical and practical philosophy are taught separately, and are separate degrees.  Other countries may use a similar scheme—some Scottish universities, for example, divide philosophy into logic, metaphysics, and ethics—but in most universities around the world philosophy is taught as a single subject.  There is also a unified philosophy subject in some Swedish universities, such as Södertörns Högskola.

His most recent work focuses on the nature of reason and reasons.  He previously taught at the University of Chicago as the "Chester D. Tripp Professor" and the "Raymond W. & Martha Hilpert Gruner Distinguished Service Professor" as well as at Columbia University.  He received his A.B. at Harvard (1972) and his Ph.D. at Yale (1978).

Anviksiki: Ānvīkṣikī is a term in Sanskrit denoting roughly the "science of inquiry" and it should have been recognized in India as a distinct branch of learning as early as 650 BCE.  However, over the centuries its meaning and import have undergone considerable variations.  In the earliest period, the term was used to denote Atma-vidya, the science of the soul, in contrast to Adhyatma-vidya, the spiritual science, or Brahma-vidya, the divine science.  In Manu Smriti the term Ānvīkṣikī has been used as equivalent to Atma-vidya and it has been described as a branch of the Vedas.  In the fourth century BCE, Kautilya in his Arthashastra recognised it as a distinct branch of learning different from Vedas and other disciplines.  Kautilya classifies all disciplines into four categories: scripture (the three Vedas, "trayi"), agriculture and commerce ("varta"), politics and public administration ("danda-niti"), and "Ānvīkṣikī", the investigative reflective science.  The distinction between Atma-vidya and Ānvīkṣikī is that while the former embodied certain dogmatic assertions about the nature of the soul, the latter contained reasons supporting those assertions.  Thus Ānvīkṣikī dealt with two subjects, namely, "atma", soul, and "hetu", theory of reasons.  The Samkhya, Yoga, and Lokayata, in so far as they treated of reasons affirming or denying the existence of soul, were included by Kautilya in the Ānvīkṣikī.  Of the two subjects studied in the ambit of Ānvīkṣikī, the study of soul later developed and matured into a separate independent study described by the term "Darsanas" (meaning philosophy), and the theory of reasons was developed into an independent branch of study referred to as "Nyaya" or logic.  This bifurcation of Ānvīkṣikī into philosophy and logic must have had its beginning in around 550 BCE with the exposition of the logical side of Ānvīkṣikī by Medhatithi Gautama.  However the term Ānvīkṣikī has been in use in the general sense of a science embracing both the science of soul and the theory of reasons.

Theoretical philosophy: The division of philosophy into a practical and a theoretical discipline has its origin in Aristotle's moral philosophy and natural philosophy categories.

Other countries may use a similar scheme—some Scottish universities, for example, divide philosophy into logic, metaphysics, and ethics—but in most universities around the world philosophy is taught as a single subject.  There is also a unified philosophy subject in some Swedish universities, such as Södertörns Högskola.
