اصل دلیل کافی: تفاوت میان نسخه‌ها

این اصل معمولاً به [[گوتفرید لایبنیتز]] نسبت داده می‌شود؛<ref>{{چپ‌چین}}There are numerous anticipations. One often pointed to is in [[انسلم]]: his phrase ''quia Deus nihil sine ratione facit''[http://12koerbe.de/pan/curdeus5.htm] and the formulation of the [[ontological argument for the existence of God]]. A clearer connection is with the [[cosmological argument for the existence of God]]. The principle can be seen in both [[توماس آکویناس]] and [[Williamویلیام of Ockhamاکام]]. Leibniz formulated it, but was not an originator. See chapter on Leibniz and Spinoza in [[A. O. Lovejoy]], ''The Great Chain of Being''.{{پایان چپ‌چین}}</ref>
