Logic and Disbelief
https://thephilosophyforum.com/discussi ... sbelief/p1
If logic is just a tool used to justify/support arguments, then how could it apply to a non-belief that is based on a lack of convincing arguments? — Pinprick
The logic of un-belief may be based on the old adage : "seeing is believing". Anything that I can't see, or otherwise verify for myself, is subjective hearsay. But most "isms" are also also grounded by a pragmatic attitude, which defines what can be accepted without evidence, and what should be treated with skepticism. Of course, it's always easy for us to be skeptical of other people's paradigms, that we don't share. And the emotional feelings of "isms", including Atheism, are often impervious to rational logic.
For example, Catholic Christians share much of their belief system with Protestant Christians, and non-christian Muslims. Yet, Catholics tend to assume that theirs is the true church, and Protestants are apostates from the truth. At the same time, the Protestant attitude is just the opposite. And centuries of rational (theological) arguments have been insufficient to overcome the feeling-of-certainty attached to their (our) beloved personal paradigms. Therefore, if a person's faith is so dependent on their subjective frame-of-reference, it behooves all of us, not just Atheists, to insist on a more objective foundation for belief, where possible.
Unfortunately, objective evidence for many human beliefs is not available. So, some things we must accept as more-or-less true (truish), as long as they don't clash with our foundational worldview. And the line-of-demarcation between Atheist and Theist beliefs usually falls into an evidence gap between the categories of "Physics" (Measurable Reality) and "Meta-Physics" (Immensurable Ideality). Ironically, many of us are more emotionally invested in subjective Ideas & Ideals, than in practical objective things, because objective facts are known only indirectly.
For example, most of us take for granted that the "solid" physical objects we see & touch are made-up of tiny balls called "atoms", because that is the conventional wisdom of classical Science. That's still true, even a century after Quantum scientists concluded from laboratory evidence -- plus lots of reasoning and arguments -- that atoms are nothing more than imaginary "balls" of mathematical probability. Like many Catholics, some of us pretend to go along with the official line (on Abortion, for instance), even as we act based on un-sanctioned beliefs. Besides, intuitive Classical Physics just feels more real than spooky Quantum Queerness, with its ghostly virtual particles.
So, what we choose to believe or disbelieve may depend more on our established belief system than on any logical or empirical evidence. And that a priori faith is your personal worldview, which in turn provides reasons for logical arguments. If the scenario of "selective truth" is indeed the case for most humans, a modicum of modesty should moderate our judgments of other people's views. And a mirror of skepticism toward our own beliefs, may help root-out fake facts.
Hume on Logic :
Hume argued that inductive reasoning (characteristic of the scientific method) and belief in causality cannot be justified rationally; instead, they result from custom and mental habit. ...
https://en.wikipedia.org/wiki/David_Hume
How can we know what's true? :
We know something is true if it is in accordance with measurable reality. But just five hundred years ago, this seemingly self-evident premise was not common thinking. Instead, for much of recorded history, truth was rooted in scholasticism.

How do we know that things are really made of atoms? :
Seeing is believing . . . or because the experts told us so?
