Looking at Daniel Novotny’s Book (2013) “Ens Rationis from Suarez to Caramuel” (Part 3 of 19)
0020 How do thought experiments work?
Typically, when reason is applied to the world of actuality, then the inquirer strives to eliminate contradictions. This is the modern way. This is the way of actuality. As soon as one poses, in reason, a scenario that does not exist (or a nonbeing) and could be regarded in the manner of actuality (or existence, being), then the logic changes from eliminating contradictions to excluding whatever makes the scenario less real.

0021 In this way, a thought experiment can find a truth within fiction.
0022 Suarez sets up what moderns call “a thought experiment”.
Allow me to go through the specifics of this thought experiment.
To start, Suarez attaches a novel normal context to the word “being”. He defines ‘a being of reason’ or beingin_reason. This beingin_reason is a nonbeing. It cannot exist. It is not a beingitself.
But, what does the word “existence” indicate?
It indicates actuality, the realm of actuality that corresponds to Peirce’s secondness.
0023 Suarez uses language to project a nonbeing into the realm of actuality. This beingin_reason is inherently a contradiction. So, reason cannot be used to eliminate contradictions. Reason must be used to explore the scenario.
0024 What is the prime motivation for doing this?
Suarez’s thought experiment allows inquiry into nonbeing. But, this is not an ordinary nonbeing, it is a nonbeing regarded in the manner of being. It does not simply not exist. It is thought of as if it does exist (as a beingitself), even though it does not.
0025 I can put this into a category-based nested form in the following manner. Reason3 is the normal context. Beingin_reason2 is the actuality. Knowing this particular character of nonbeing1 is the inherent possibility.

0026 How relevant is this nonbeing stuff?
Needless to say, I personally think that there are more reasons for asking about beingsin_reason than nonbeing, comparison, and holding contradictions in thought.
One motivation concerns — what I call — implicit and explicit abstraction. The idea comes from An Archaeology of the Fall.
In the Lebenswelt that we evolved in, our genus and our species practiced hand talk. Hand talk favors implicit (or intuitive) abstraction.
In contrast, in our current Lebenswelt, speech-alone talk permits explicit (or symbolic) abstraction.
0027 In order to get a picture of the difference between hand talk and our current way of talking, speech-alone talk, consider the following associations:

0028 I ask, “Which row goes with hand talk? Which row goes with speech-alone talk?”
Let me give you a hint.
In hand talk (and in its more developed hybrid, hand-speech talk), words consist of what could be imaged or pointed to. Manual-brachial word gestures are ideal for picturing and indicating things and states of things.
In speech-alone talk, word-sounds do not image or point to anything. Spoken words are placeholders in two arbitrarily related systems of differences. A word-sound is a placeholder linked, by convention, to a place-holding word-mental act. One symbol links to another. One symbolic order evokes the other.
