\bigskip


The title refers to two aspects of Fisher's legacy: his essential role in
the founding of modern statistical theory, and also to the essence of his
approach that differentiates it from frequentist and Bayesian methods.
Fisher's ideas are particularly dominant in estimation
theory and its applications. However I will also discuss hypothesis testing
and model selection, where, despite the enormous influence of Neyman and
Pearson, Fisher's scale of evidence (".05 significance level", etc)
continues to dominate statistical practice.  A subtitle for this
last topic might be "Fisher's famous debate with Jeffreys that never happened."
