LakatosVsPopper: falsification (ism) ("Man proposes, nature disposes") cannot be right, because it presupposes the distinction theory/observation.

2. that observation sentences could be proved by facts.
>Theory, >Observation, >Observation sentence.

LakatosVsPopper: Theories are never rejected on the basis of a single counter-example, but they are adjusted.
>Progress.
