《Tetrabiblos》That Prescience Is UsefulClaudius Ptolemy（Ashmand 英譯 1822）
And therefore all events which happen to mankind take place also in the regular course of nature, when no impediments thereto are found or known: but again, on the other hand, if any impediments or obstructions be found in the way of events which may be predicted by the regular course of nature to happen, such events will either not take place at all, or, if they should take place, will be much diminished in their force and extent.
