Stigler's contribution was enlightening. With his added sense of humor, it made it a memorable event.

To put some perspectives into the 7 pillars let me share my views and perspective on all this.

In his 1922 fundamental paper in the Philosophical Transaction of the Royal Society (Ser. A, 222, pp. 309-368) Fisher states that "the object of statistical method is the reduction of data". He then identifies "three problems which arise in the reduction of data". These are:
1. specification - choosing the right mathematical model for a population
2. estimation - methods to calculate, from a sample, estimates of the parameters of the hypothetical population
3. distribution - properties of statistics derived from samples.
Later, Colin Mallows, a distinguished researcher at AT&T Bell laboratories, added a "zeroth problem" - considering the relevance of the observed data, and other data that might be observed, to the substantive problem (Mallows, 1998).

Stigler seems to have expanded on these 4 pillars and redesign 7 interesting pillars with relevance to the scientific. In a wider sense. more is needed. Some attempts to consider the contribution of statistics to business and industry, with a life cycle view, is available in http://ssrn.com/abstract=2315556
