真确的

A theory cannot be tested by its realism of assumptions, but on its observable implications and predictive power.

而一个理论的重点并不在於解释其假设中的断言，有时我们甚至连其假设的真确性也不易去验证（这或许是因为人本身的限制所致），我们只可以从其引伸出来的含意和推断能力去验证这个理论。

Complete liberty of contradicting and disproving our opinion, is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right.

我们之所以可以为着行动之故而假定一个意见的真确性，正是以有反对它和批驳它的完全自由为条件；而且也别无其他条件能使一个象具有人类精神能力的东西享有令他成为正确的理性保证。
