A necessity for one thing to happen because another has happened does not exist. There is only logical necessity.
6.371 At the basis of the whole modern view of the world lies the illusion that the so-called laws of nature are the explanations of natural phenomena.
6.372 So people stop short at natural laws as something unassailable, as did the ancients at God and Fate.
And they are both right and wrong. But the ancients were clearer, in so far as they recognized one clear terminus, whereas the modern system makes it appear as though everything were explained.
6.373 The world is independent of my will.
6.374 Even if everything we wished were to happen, this would only be, so to speak, a favour of fate, for there is no logical connexion between will and world, which would guarantee this, and the assumed physical connexion itself we could not again will.
6.375 (1) As there is only a logical necessity, so there is only a logical impossibility.
