There is a diffuse sentiment that to anthropomorphize is a mild vice that people tend to do easily and pleasingly, but that an adult well educated person should avoid. In this paper it will be provided an elucidation of ``anthropomorphism'' in the field of common sense knowledge, the issue of animal rights, and about the use of humans as a model in the scientific explanation. It will be argued for a ``constructive anthropomorphism'', i.e., the idea that anthropomorphism is a natural (...) attutude to attribute human psychological features to other individuals, no matter they are actually rational agents, or not. If we know the ``grammar'' of this attutude, we can avoid the risks in overestimating the environmental inputs towards anthropomor­phism and, at the same time, take the heuristic advantages of anthropomor­phism in the use of human mind as a model for both everyday circumstances and scientific enterprise.
