One of the world's oldest philosophy books records a woman as its fiercest cross-examiner
The Bṛhadāraṇyaka Upaniṣad — among the oldest philosophical texts ever composed, older than the classical philosophers of Greece — stages a public debate at the court of King Janaka in which the woman scholar Gārgī Vācaknavī rises to cross-examine the sage Yājñavalkya, pressing him question after question on what the universe is 'woven upon.' She is the only challenger in the account to question him twice. It is one of the earliest recorded philosophical dialogues anywhere, and one of its sharpest interlocutors is a woman.
How we know
The Gārgī–Yājñavalkya exchange is preserved in the Bṛhadāraṇyaka Upaniṣad (3.6 and 3.8), set at the assembly of King Janaka of Videha. The Upaniṣad is dated by Olivelle to roughly 700 BCE, well over two centuries before Socrates (c.470–399 BCE). Gārgī is described as a brahmavādinī; she presses Yājñavalkya hardest of all the challengers before conceding the contest.
