The nature of evidence

[Mister Agenda]

The type of reasoning we use to get from facts to a conclusion is inference. For instance, I can breathe and am aware of my breathing. From my experience in general and some basic knowledge of biology and physics; I can use that fact to conclude there is breathable air in the room, I am alive, I am conscious, the air contains a fairly high percentage of Oxygen and a fairly low percentage of Chlorine; and so forth.

Boolean logic withdraws its support pretty quickly when we start to go past what we know and it disappears on us entirely when we delve into what we can't know.
