What was the foundation of mathematics?
Were they the ten digits from 0 to 9?
No, they were not. Before learning to recognize those ten digits, one had to learn to distinguish their relative sizes.
To determine "large" and "small" was to determine "whether a number belonged among those smaller than a certain number."
More fundamental than numbers was logic.
"Grasp 'yes' and 'no,' and you have grasped the 0 and 1 within a computer. Only this... cannot be lost!" As he thought, Wang Qi was interrupted several times by memories of the past. "Since my memories are already in chaos, I might as well give up sorting them out!"
"Whether they are from my previous life or this one, ignore them all. Don't think about them! So long as it is 'experience,' discard it outright!"
"And if it is 'knowledge' that I cannot understand for the time being, discard that as well!"
After establishing the great premise of "who am I," Wang Qi was able to keep his true heart unshaken and his true spirit undimmed amid the impact of the entropy flow. After that, he used mathematical logic and set theory to rebuild "order" within his consciousness!
"At the beginning, the most basic logic is a single judgment of 'yes' and 'no'—judging whether something belongs to set A..."
"'Or,' 'and,' and 'not' are three judgments involving two sets: 'whether it belongs to set A,' 'whether it belongs to set B,' and 'whether it belongs to both set A and set B'..."
When ordinary people encountered a surge of inner demons, they would mostly choose visualization. They would visualize Sword Intent cutting down the inner demons, visualize Yue Luo Liuli flames burning the inner demons to ashes, and so on. Wang Qi's deduction of logic was, in essence,
