Abstract
Understanding the structure of logic defies the narcissistic delusion that the human brain can do fabulous and wondrous things\(\tm\), which is particulary and painfully false.
Or as a dear relative phrased it:
Well, they say “You can lead a horse to the water …”, but these people – they do not just not drink – they turn around and shit in the water. At least by the time they reach their master’s degreee, they have slowly come to realize that they don’t know shit – that all their ideas are shit – and that they need to behave accordingly.
I know, that I cannot know.

Hypothesis: The vast desert of NAND is utterly incomprehensible.
Let there be proof, let \(\neg\) be NOT, \(\wedge\) be AND, \(\vee\) be OR, \(\rightarrow\) be IF, \(\uparrow\) be NAND, as defined by the following excerpt of the truth tables for binary truth functions:
\(f^{2}_{12}\) | \(f^{2}_{10}\) | \(f^{2}_{1}\) | \(f^{2}_{7}\) | \(f^{2}_{13}\) | \(f^{2}_{14}\) | \(f^{2}_{1} (a)\) | \(f^{2}_{7} (b)\) | \(f^{2}_{12} (c)\) | \(f^{2}_{13} (d)\) | |||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
\(p\) | \(q\) | \(\neg p\) | \(\neg q\) | \(\wedge\) | \(\vee\) | \(\rightarrow\) | \(\uparrow\) | \(\neg (p \uparrow q)\) | \(\neg p \uparrow \neg q\) | \(p \uparrow p\) | \(\neg p \vee q\) | |||
0 | 0 | 1 | 1 | 0 | 0 | 1 | 1 | 0 | 0 | 1 | 1 | |||
0 | 1 | 1 | 0 | 0 | 1 | 1 | 1 | 0 | 1 | 1 | 1 | |||
1 | 0 | 0 | 1 | 0 | 1 | 0 | 1 | 0 | 1 | 0 | 0 | |||
1 | 1 | 0 | 0 | 1 | 1 | 1 | 0 | 1 | 1 | 0 | 1 |
Henceforth the compound phrase
defined by its atomic member statements
gives rise to the symbolic representation
With a couple of well-known simple laws, namely
proved by full induction over the truth tables, formula (2) is transformed to
Replacing NAND expressions with different language constructs
for each parenthesized level, assigned to the deepest innermost level first, formula (4) translates to
Although parentheses are kept as structural support, even providing indentation for clarification, the statement’s translated form (6) still makes the issue at hand utterly confusing, if not completely incomprehensible for a human brain.
So, while the human brain is able to produce such fabulous and wondrous things, it is not capable of understanding such fabulous and wondrous things, which would have been truely fabulous and wondrous. But this is not the case. Therefore humans are basically on the same level as monkeys randomly typing on typewriters, producing all of Shakespeare’s works eventually \(\blacksquare\).
To the unsuspecting eye the phrasing of the NAND statement (6) may appear as a complete denial – even asserting ultimate falsehood – although it is in fact – just like its original form (1) – always true.
