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）断言为不可废止这一重要实。

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.

独自一人在这个世界， 被它抛弃了，有了这个唯一宝物来维心， 觉得拥有对抗这个世界不可剥夺权利， 并准备誓死捍卫它们。
