Arguments and evidence
Arguments are not evidence.
Aquinas wrote startingly long arguments in his summa theologicae. Logically consistent, thorough, detailed, and organized arguments they were. As an almost random example:
"On the contrary, the Apostle says, 'the invisible things of Him are clearly seen, being understood by the things that are made' But this would not be unless the existence of God could be demonstrated through the things that are made; for the first thing we must know of anything is whether it exists.
I answer that, Demonstration can be made in two ways; One is through the cause, and is called "a priori," and this is to argue from what is prior absolutely. The other is through the effect, and is called a demonstration 'a posteriori"; this is to argue from what is prior relatively only to us. When an effect is better known to us that its cause, from the effect we proceed to the knowledge of the cause. And from the every effect the existence of its proper cause can be demonstrated, so long as its effects are better known to us; because since every effect..."
And so on.
Much of medieval thinking focused on the proof of what was already "known". What was known was obvious and arguments were designed to support the known revealed truth. Almost as an afterthought, a few examples from the natural world might be shown. Brilliant but deductive thinking all around. 'We know what is true, this argument proves the truth, and this example demonstrates the truth."
Inductive reasoning was quite contrary to medieval thought. The method of initial observation of the natural world, followed by the organization of these observations, thinking/reasoning about them, and then inducing conclusions about natural reality is not a method whereby medieval thinkers came to their reality.
Deductive reasoning makes it easy to look at the Grand Canyon USA and "see" the effects of an ancient mediterranean flood.
