To do this fairly we grant the stipulation that everything in the universe is explicable, or will ultimately be physically explicable. 为了公正起见,我们同意这样的假定:宇宙中的一切都是可以解释的,或者最终都将得到物理学上的解释。
The association should be coherent; that is, plausible and explicable biologically according to known facts in the natural history and biology of the disease. 相关性应是合理的;也就是说,根据疾病的自然史和生物学上的已知事实,可以从生物学角度来解释相关性。
