In Aristotle’s bk. 1Posterior Analytics ch. 3, he says:
To which St. Thomas Aquinas says in his , lib. 1 l. 7Expositio Posteriorum:Some hold that, owing to the necessity of knowing the primary premisses, there is no scientific knowledge. Others think there is, but that all truths are demonstrable. Neither doctrine is either true or a necessary deduction from the premisses. …] Our own doctrine is that not all knowledge is demonstrative: on the contrary, knowledge of the immediate premisses is independent of demonstration.
Does this mean that the “science of principles is possessed” by faith? Would not this be fideism, since it “affirms that the fundamental act of human knowledge consists in an act of faith” (Sauvage, G.)? Since St. Thomas says that “faith is more certain than science and the other intellectual virtues” ( IIª-IIae q. 4 a. 8Summa Theologica), which is good if “demonstration must be based on premisses prior to and better known than the conclusion,” as Aristotle said" in the above-cited chapter of his Posterior Analytics, is it proper to say “Science, therefore, is grounded on faith?” Is this a type of fideism? Read this for more background. ThanksTherefore, if someone were to ask how the science of immediate principles is possessed, the answer would be that not only are they known in a scientific manner, but knowledge of them is the source of a science. For one passes from the knowledge of principles to a demonstration of conclusion on which science, properly speaking, bears. But those immediate principles are not made known through an additional middle but through an understanding of their own terms. For as soon as it is known what a whole is and what a part is, it is known that every whole is greater than its part, because in such a proposition, as has been stated above, the predicate is included in the very notion of the subject. And therefore it is reasonable that the knowledge of these principles is the cause of the knowledge of conclusions, because always, that which exists in virtue of itself is the cause of that which exists in virtue of something else.
