Thus I am not disputing this vital fact which the classical economists have (rightly) asserted as indefeasible.

因此，我不是在质疑古典经济学家（正确地）断言为不可废止的要实。

Alone in the world, cast off by it, and with this sole treasure to keep her heart alive, she felt that she possessed indefeasible rights against the world, and was ready to defend them to the death.

自人在个世界上， 被它抛弃了，有了个唯的宝物来维持她的心， 她觉得她拥有对抗个世界的不可剥夺的权利， 并准备誓死捍卫它们。
