  • 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.
