  This paper addresses a very classical topic that goes back at least to
Pl\"ucker: how to understand a plane curve singularity using its polar curves.
Here, we explicitly construct the singular points of a plane curve singularity
directly from the weighted cluster of base points of its polars. In particular,
we determine the equisingularity class (or topological equivalence class) of a
germ of plane curve from the equisingularity class of generic polars and
combinatorial data about the non-singular points shared by them.
