The chicken noticed that the farmer came every day to feed it. It predicted that the farmer would continue to bring food every day. Inductivists think that the chicken had "extrapolated" its observations into a theory, and that each feeding time added justification to that theory.

From this fact it is a highly probable inference that there is also nowhere a very wide mental gap.
