[filed under theme 14. Science / A. Basis of Science / 4. Prediction ]

Full Idea

There can be explanations without predictions, as when we explain a previous position of Mars from its present one, plus a law.

Gist of Idea

If we say where Mars was two months ago, we offer an explanation without a prediction

A Reaction

If we don't mind stretching the word, I think we can 'predict' the past, as where I predict the location of an Egyptian tomb from my study of papyruses.
