The Meaning Of Is
Posted in Misc., Objectivism, Language on March 27th, 2008While parsing random thoughts in the shower this morning, the notorious phrase of evasion, “It depends on what the meaning of the word ‘is’ is.”, popped into my head. For the first time that I can recall, I actually paused in an attempt to accurately articulate a response to the question. Here’s the best I could do without consulting a dictionary. I must also note that I’m winging this without a complete understanding of Objectivist epistemology. I hesitated to publish my thought process at first, but then decided it would be a valuable experience to learn from any flaws that are exposed. I’m certainly not afraid of being corrected, since a breach of the solidity in my low-level thinking will only cause intellectual strife above. Doing something my own way, only to be corrected and shown the right way, has always proven to be a very valuable way for me to acquire knowledge. Not only do you learn from the correction, but a close examination of how you came to the conclusion you did, and an abstraction of the error can save you from similar mistakes in future endeavors. I will most likely look back at this and laugh at some point in the future.
is -auxiliary verb: an expression of affirmation regarding one, many, or all attributes of an entity’s identity.
Considering this definition of it’s meaning and usage, how does it relate to communication, and more specifically, for communication that should be considered as a reliable means of acquiring knowledge? For the assertion to be accepted, a complete inventory of it’s associated evidence must be considered. Once the evidence is considered, we categorize the assertion as true, probable, possible, improbably, or false. The amount of evidence needed in order to 1) find the assertion worthy of even considering, and if so, 2) consider the assertion reliably, is based on the amount and nature of any contextual insight needed.
The need for contextual insight will vary according to the nature and complexity of the attribute(s) being affirmed. The amount of context required is inversely proportional to the degree of self-evidence. Thus, an absolutely self-evident claim, “A is A”, would require no contextual insight. Conversely, an absolutely contradictory claim, “A is not A”, would require infinite contextual insight because it could never be rationally justified. Within polar opposites there would be assertions which would need infinitely varying degrees of contextual insight. In more concrete forms, the phrase “Brad is alive” would require no contextual insight on my part as it is absolutely self-evident. The phrase “The dog is barking” would require very little insight considering this is a normal behavior for dogs. “The dog is flying” would lead me to gather more insight (is the dog on a plane?), and “The dog is speaking Portuguese” would require a substantial amount of contextual insight. Finally, “The dog is a cat” (a contradiction) is inexplicable, and could not be accepted on any amount of contextual insight.
The distinction between metaphysical facts, ones that exist in truth outside of any volitional consciousness (“The rock is gray.”), and man-made facts, ones that exist only in the context of a volitional consciousness (“Betty is Wilma’s best friend.”), is the metric by which an assertion’s degree of self-evidence can be judged.
Contextual insight can exist as information that was previously obtained by concept integrations (knowledge), or as first-hand perceptual evidence (concepts integrated real-time to form contextual certainty). One familiar with frogs may be able to accept the assertion that “Dendrobates Azureus is blue with black spots” because their knowledge provides the contextual insight, whereas an individual who’s unfamiliar with South American Amphibians may require first hand visualization.
The last key element serving as contextual insight is the reliability of the individual making the assertion, which is the sum of a tremendous number of possible variables. The first to mind are:
- Who are they?
- Why would they make the assertion?
- Are they usually correct?
- Is this a subject that they are knowledgeable in?
Each of these fairly broad criteria obviously are built on numerous other factors, all which must be considered and calculated at light speed when we encounter an assertion using the word ‘is’. This is beginning to wander a bit in to areas that are well beyond the scope of this post and my knowledge, so I’ll wrap it up.
It’s easy to poke fun and make light of the original question until you think about what a blatant evasion it is - a sassy attempt to play semantics with the law of identity. ‘Is’ implies identity.
