  1. 1Around 1027Ibn Sina — Experience with repetition and conditions

    Ibn Sina · Demonstration from The Cure

    Does extensive repetition yield absolute universality, or only a strong judgment within specified conditions?

    `al-Burhān` I.9 distinguishes `istiqrāʾ`, which enumerates limited cases, from `tajriba`, which joins repeated sense experience with inference.

  2. 21748Hume — Distinguishing expectation from proof

    David Hume · An Enquiry concerning Human Understanding

    Even if repetition explains expectation, does it prove that the future must resemble the past?

    Past experience directly concerns the objects and periods observed; extending it to similar new objects and future periods requires a further inference.

    John Stuart Mill · A System of Logic

    Can one well-designed contrast provide stronger grounds than a thousand identical records?
