I proclaimed the importance of this second variance, infinite variance, very loudly and in general a view of inequality, irregularity, which was very, very unpopular. It's very easy to explain actually and it's very important. Imagine that you take two molecules of a gas, and you find that the total energy is u; then you know perfectly well that each of them has a energy which is u over half, plus or minus a small fluctuation, which actually is Gaussian, more or less. In other words, in classical physics, there is a very profound situation, which is equality plus or minus a small fluctuation. But now imagine on the contrary that you walked down Wall Street and you're allowed to stop two persons more or less blindly and find that the total income for the year 1997 was two million dollars. Now are you going to say that you have found two millionaires? Of course not. Everybody has the absolutely strong conviction, perfectly justified, that most likely one of them is an ordinary wage earner -again distribution - maybe twenty, fifty, maybe a hundred thousand dollars, and the other has all the rest. Therefore the inequality was not something that was in a certain sense quantitative, but qualitative. In one case one half plus or minus, in the other case its two independents, one point which is independent of a sum, and then the other which is the rest. Now, at that point I was very much in a mood already to attribute more importance to qualitative than to quantitative distinctions, because the qualitative one is so sharp it would separate two very different behaviours. If it were just qualitative matter- up to a point it is a liquid and after it's a gas - it wouldn't be right - the critical points would be terrible, they're too complicated.
