Nociones alternativas, legalidad y causalidad: una discusión

Abstract

The aim of the current work is to contribute in the search for a theory within which alternative conceptions can be described and predicted. We try to evaluate the degree in which Piaget's causal operations are useful in this respect. We have chosen one subject which we use for our examples: floating bodies. We follow Piaget's discussion starting from his early works and we use it to exemplify and discuss certain subtle diferences between legality and causality which are central according to this autor.
