  • What is truth?

    There’s inductive and deductive reasoning. If axioms are true, theorems arrived at by deductive reasoning are almost certainly true. (Although Gödel cast doubt on even this.)

    Science is based on inductive reasoning. No amount of evidence confers certainty. I’m amused when someone proclaims a theory as truth. They demonstrate their ignorance of the philosophy of science.

    Moreover, often consensus is wrong. For example, prior to the Alvarez father and son team, a meteorite wiping out the dinosaurs was considered a crackpot fringe notion. Then the Alvarez found high levels of iridium at the KT boundary throughout the planet. Now it’s generally accepted an impact caused the extinction of the dinosaurs.

    It is clueless to declare current consensus to be the truth.

      I was not aware, 2 yrs ago, about this post, or I would have commented then.
      “I’m amused when someone proclaims a theory as truth”…here’s the problem, someone writes
      crap when they don’t even know what they are talking about.
      Evolution, as an example, means change over time. That is a fact. Over 150 years of overwhelming
      evidence to support that. The theory is natural selection, which by the way, has been the best explanation from the data of facts. Now, the theory could someday be overturned…by new evidence.
      If you don’t like the theory, then go out and find the new evidence AND win a Nobel Prize (and I am not kidding). Evolution is a FACT. The theory is based on inductive reasoning, yes. “There are no black swans” is also inductive reasoning and quite logically made sense to accept until a black swan was found, and then our thinking changed. I have no problem with that.
