The Nyaya-sutras are attributed to Gautama, who was at the very least the 
primary author. According to Karl Potter, this is a very common Indian name, and 
the author is also known as Gotama, Dirghatapas, and Aksapada Gautama. Little 
is known about Gautama or the century in which he lived. Based on textual 
analysis, scholarly estimates range from the 6th century BCE, making him a 
contemporary of Gautama Buddha (Siddhartha Gautama) and Mahavira, to the 
2nd century CE. Some scholars believe that the cryptic text Nyaya-sutras was 
expanded over time by multiple authors, with Gautama contributing the first 
layer around the mid-first millennium BCE.
