“How Can We Know What The Probability Is?” And Other Objections And Remarks

The following, of course, is not yet developed.

“Where did you get that 99% probability from?” someone may object.  “Did you pull it from your ass?”  Well, I did stipulate it.  But the general objection remains valid nonetheless:  it would seem that there is no way to come up with an objective evaluation of what the probability actually is unless it is 0 or 100%, these figures being based on the physical laws of the universe or the laws of probability.  Deal with this.  See if Dretske’s discussion of this works.

Inductive:  probability of less than 100% but greater than 0.  Deductive (or what supports deduction):  conditional probability is 100%.  Absolute reliability, absolute safety.  What makes the transmission a case of information is also what makes it something supporting deduction.

IF p THEN p — either a complete lack of transmission of information or the exact opposite — a complete surfeit of “transmission” (quote unquote) at the “zero point”.




About Cliff Wirt

I am a banking DBA with various and sundry interests, including art, poetry, philosophy, music, languages, relational algebra, database administration, and blueberries. Don't forget the blueberries. Some of these interests tie in in surprising though usually tangential ways with database theory. Even the blueberries. I have published one article in a Philosophy Journal, and I have one painting in a corporate collection (housed in what used to be the Amoco building in Chicago). According to 12andMe, my paternal haplogroup is I2, my maternal H5. The Neanderthal percentage of my ancestry is 3%. My most famous ancestor is William Wirt (from whom I get my last name, though possibly not my Y chromosome), who defended the rights of the Cherokees before the Supreme Court, and ran for President in 1832, carrying one state.

  • What Is Relevance Anyhow? | cliffengelwirt

    […] Although Madame Olensky’s standing over the body of Professor Plum with a smoking gun definitely increases the probability that she is the murderer of Professor Plum beyond 0, that probability is doubtlessly not 1.  For a sufficiently competent writer of mystery novels can invent a scenario just barely within the realm of possibility in which, despite the bald fact that Madame Olensky is standing over the body of Professor Plum with a smoking gun in her hand, she is in fact not the actual murderer of Professor Plum.  The probability is, say, a mere 0.99999999999.
