Gautama Dharmasutra

"The witness must take an oath before deposing. Single witness normally does not suffice. As many as three witnesses are required. False evidence must face sanctions."

"He should not spend the morning, midday or afternoon fruitlessly, but pursue righteousness, wealth and pleasure, to the best of his ability, but among them he should attend chiefly to righteousness."

"The Dharma-Shâstras give a completely far-fetched theory of the origins of the castes, e.g. the Gautama-Dharma-Shâstra (4.17) relays the view that the union of a Shûdra woman with a Brâhmana, a Kshatriya or a Vaishya man brings forth the Pârashava c.q. the Yavana (‘Ionian’, Greek or West-Asian) and the Karana jâti."
