In electrical circuits, ground is the point of reference for the voltages of the rest of the nodes in the circuit. It is the one point in the circuit which has a known, established voltage: zero volts. The absolute voltage of any circuit node is determined by measuring its voltage with respect to ground. For different circuit stages to work deterministically with each other, they need a common ground, a conductor with low impedance so that the physical voltage on the ground conductor remains as close to zero as possible. With a good common ground, circuits can be made to interface with each other.
If the grounds between stages of circuitry (systems) are not common, i.e. the voltages between the grounds for each stage is not zero, then it is not possible to know how one circuit relates to the next, and failure is guaranteed.
Any electrical designer who ignores his grounds is in for a heap o’learning.
Now let’s consider philosophers. Many philosophers like to say that philosophy is the rational analysis of arguments. Or some variation on that. Supposedly an argument is made, say that,
“If P is true, then Q is true;
P is in fact true;
therefore Q is true”.
So far so good… except is P really, in fact, true?
In order to know if P is true (to support the contention that Q is true), we need another argument:
”If N is true, then P is true;
N is in fact true;
therefore P is true”.
But is N really, in fact true? We must find yet another argument to support N, and so it goes. It could go on forever, in an infinite regression of arguments which never reaches a known “true” by self-evidence, or by definition, or by some other form of unquestionable authority.
Or perhaps the argument chain actually turns around and refers to the original argument as a source of support. This is self-referential, and it, too, never terminates in a known “true” by self-evidence, or by definition, or by some other form of unquestionable authority.
The third possibility is that the chain of arguments does in fact terminate in a statement which is a known Truth. This terminating statement is a “ground”, or an absolute axiom which supports the argument which refers to it. So if the chain of arguments which terminates in such a ground is valid at all points, i.e. the logical format is correct, then the original argument can be known to be correct. And this is the only option of the three possibilities which contains that knowledge; the infinite regress and the circular arguments cannot produce knowledge.
Interestingly, Philosophers in general reject the existence of grounding Truths. So where does that leave the truth value of their declarations? Without some sort of inflexible guiding principle, some veridical axiom, some inviolable, incorrigible, external ground, all thoughts become relative, floating in a tide of unknown and unknowable, non-existent truth.
The result is an attempt to create a truth out of nothing, ex nihilo, just by thinking really hard about it.
DESTRUCTION of REALITY
Bertrand Russell concluded that there is no way to refute hard Skepticism, that which denies that reality exists. (Brain in a vat, etc.) He also said that he wished that all those who deny reality would get into their automobiles, drive straight into a tree, and then defend their Skepticism.
But the intellectual attempt to destroy reality is based on the need to eliminate the concept of grounding. Hence the theories that consciousness doesn’t exist, that “self” doesn’t exist, that agency doesn’t exist, etc. Materialist reductionism is absolutely necessary if the physical limit on existence is to be maintained. And the physical limit is to be maintained at all cost – no non-physical existence can be allowed a foot in the door. That would destroy the ideology.
So the ground for Philosophical Materialism is just this:
” There is NO non-physical existence, period”.
How does this statement stand up as an absolute ground for every and all arguments? Is there evidence for this statement? Is it incorrigibly self-evident? How about its corollary:
All things are physical and therefore are subject to Cause and Effect.
Is there evidence for this statement? Is it incorrigibly self-evident?
These are not observed facts, they are desired outcomes which are desired in order to protect an ideology which requires them to be true. Under these “principles” it is necessary to declare and somehow prove that certain non-physical things are, in fact, physical. Or failing proof, to claim that they do not even exist, being illusions or delusions.
Here we have the case where the grounds of Philosophers do not match the grounds of logicians: the First Principles. (While philosophers might claim to be logicians, they abandon logic immediately when it contradicts their ideologies).
Taking the first Materialist ground, ” There is NO non-physical existence, period”, this statement is a proposed principle, a supposed axiom. Principles do not physically exist in nature; they are intellectual constructs, created to demonstrate a proposed universal truth. So the statement itself is not physical. And its meaning is not physical. If the statement has any meaning at all, then it contradicts itself, and thereby runs afoul of the First Principles of Logic and Rational Thought, specifically the Principle of Non-Contradiction.
So at this point one must choose (or walk away befuddled) between the Materialist ground or the Logician’s ground.
Or try desperately to prove that a principle is either a physical object or doesn’t exist at all, that meaning is either a physical object or doesn’t exist at all, or some other obfuscation to try to eliminate the obvious conflict.
The gulf is even wider between those who declare ethical standards for us, and those who want grounded moral standards. As the great Arthur A. Leff pointed out, an impeccable ethical standard requires an ethical standard giver who is beyond reproach, beyond question, perfectly ethically impeccable in every way. When a philosopher declares an ethic, Leff points out that the proper response is, “Sez Who? Who sez so, and who are you to say so? What exactly gives you the right to determine any ‘standards’ for me?”
If there is no human who can be shown to be unquestionably morally impeccable, then there is no Ground for any human-declared ethic. What we must have for an impeccable, unquestionable ethic is a “Grand Sez Who”. Otherwise, ethical posturings are merely the ungrounded opinions of certain humans regarding how they think the rest of us should behave.
It is the lack of grounding in philosophical and ethical thought which destroys the value of philosopher’s maunderings. If all philosophical arguments are infinite regresses or circular, or in the case of ethics - just opinions, then they are totally without truth value. But because of the perceived eliteness of these “thinkers”, their output is given far too much value in the popular culture. Untethered thinking leads to nihilism and hedonism, a fact demonstrable in our current culture. Lacking grounding is dangerous.
I remember the first television attack on moral grounding, the sit-com “All in the Family”. Liberal notions were given logical, loving overtones while grounded ethical notions were depicted as hateful, bigoted and stupid. The first ungrounded movie was “Water Hole #3”, a western comedy which had no good guys, only bad guys and worse guys. It was funny in a guiltless, amoral sort of way. (note 2) After that movie, the white hats were portrayed as stupid bigots or not at all.
During the ‘70’s, the boomers became the Me Generation, grounded only in themselves and nothing else. The national currency was completely ungrounded by the final removal of reference to gold by Nixon (started under FDR). Easy credit was the ungrounding of spending based on income and actual net worth. The "dot.com" bubble was the ungrounding of value based on actual profit. The housing bubble was the ungrounding of mortgage approval based on income and ability to repay. The list of ungroundings goes on and on, and it is not positive.
The final ungrounding is the loss of rational thought, which is replaced by rationalized thinking. Untethered thought leads straight to Nietzsche’s Anti-rationality, whether it is recognized or not. Anti-rationality leads to emotionalism, the “I want” which is displayed in Materialist and Leftist mantras. And that’s where we are now. “I want this to be true, so it is true… for me”.
Addendum
The ungrounding of the meanings of words is a recent phenomenon, useful in defending irrational ideology. Or is it new:
'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean — neither more nor less.'
'The question is,' said Alice, 'whether you can make words mean so many different things.'
'The question is,' said Humpty Dumpty, 'which is to be master — that's all.'
