Ga?ge?a
(
Sanskrit
:
?????? ????????
,
Ga?ge?a Up?dhy?ya
) (first half of the 14th century) was an Indian
philosopher
,
logician
and
mathematician
from the
kingdom
of
Mithila
. He established the
Navya-Ny?ya
("New Logic") school. His
Tattvachint?ma?i
(The Jewel of Thought on the Nature of Things), also known as
Pram??acint?ma?i
(The Jewel of Thought on the Means of Valid Knowledge), is the basic text for all later developments. The
logicians
of this school were primarily interested in defining their terms and concepts related to non-binary logical categories.
Life

Ga?ge?a was a native of the
Mithila region
in modern-day
Bihar
.
[1]
He seems to have been born and raised in a village called Chadana however this is no longer identifiable. He later lived in the village of Karion, the same village that fellow philosopher,
Udayana
came from which is twelve miles southeast of the city of
Darbhanga
.
[2]
Scholars have struggled to find an accurate date for Ga?ge?a with the most common estimate placing him in the late thirteenth century however recent opinion now places him in the fourteenth century.

The
Tattvacint?ma?i
[
edit
]
The founding text of Navya-Nyaya - it is divided into four kha??as (books): Pratyak?akha??a (book on perception), Anum?nakha??a (book on inference), Upam?nakha??a (book on comparison) and ?abdakha??a (book on verbal testimony). The first book opens with a salutation to Shiva.
[3]
The Tattvacint?ma?i (T.C.) is a systematic account of epistemology, logic, and the philosophy of grammar. Other subjects, such as the proofs of God, are treated incidentally.
Gangesa refers to his own teachings as the New Nyaya. This term New Nyaya is not to be understood as implying any great originality in theory on Gangesa's part, but rather originality in method. His work differs from the oldest Nyaya in that he accepts many tenets of the Vaisesika school, and in his arrangement of Nyaya teachings under four headings rather than under the 16 subjects (
padartha
) of the Old Nyaya.
The newness of Gangesa's method is newness of style and of organization. He is far more precise, more careful to define his terms, than were his predecessors; these virtues of his work are responsible for the fact that perhaps half of Navya-Nyaya literature is based either directly on the T.C. or on a commentary on the T.C.
