The process of going from a set of observations to a generalisation See multiple objects with a characteristic X, all such objects have characteristic X The sun rose every morning already (every observed morning had the characteristic that the sun rose) … so the sun will rise every morning, so tomorrow the sun will rise again “The future will behave like the past”

Ideas/ knowledge can only change in 3 ways: Preventing them from changing: you secure them from changing by justifying their truth, by adding arguments to them that say why they are true, e.g. appeal to authority arguments.
