Abstract: Let $K$ be an $n$-dimensional symmetric convex body with $n \ge 4$ and let
$K\dual$ be its polar body. We present an elementary proof of the fact that
$$(\Vol K)(\Vol K\dual)\ge \frac{b_n^2}{(\log_2 n)^n},$$ where $b_n$ is the
volume of the Euclidean ball of radius 1. The inequality is asymptotically
weaker than the estimate of Bourgain and Milman, which replaces the $\log_2 n$
by a constant. However, there is no known elementary proof of the
Bourgain-Milman theorem.
