lOGICal ?

I haven’t been asked any question about the name ‘rational fool’ or ‘logical fool’, because of the limited audience of blog. But I am going to explain it anyway. First of all going backward the word ‘fool’, now a point should be noted that at micro level it  does not mean lack of intelligence. I know that, I am not less fortunate in terms of intelligence. Robert J. Sternberg states that “Foolishness is the lack or failure of wisdom and of making proper careful choices. In this sense, it differs from stupidity, which is the lack of intelligence”. But the major dilemma here is not that about how an intelligent person can be fool, it’s how a rational person can be a fool. Any rational decision taken with pure logic, can be wrong horribly wrong as we human are not omniscient, we have a limited view of environment and so any rational decision can be wrong. A superb example was found in the our reference book of Artificial Intelligence(Russel-Norwig, Pearson 2e). If I am walking on the pavement of the road and on the other side I see and old friend also walking. I do not have any hurry and he also seem to be relaxed, so its rational to go on the other side and meet him. I check on both the side before crossing the road, its empty. Now crossing the road is a fully rational decision. But as I start crossing the road, a aero plane flying 35,000 feet above me loses a cargo. Which eventually falls on me at the middle of the road. Needless to say, what happens to me. Now this decision to meet an old friend and crossing the road, however horribly wrong(we will define right decision as the one beneficiary to me, and wrong the opposite) was not ‘foolish’. But in real life, sometimes decision made with logic and rationality in mind turns out to be foolish, or feel foolish afterwards. Another meaning which was not exactly in my mind when acquiring this name, is ardent enthusiast about something. But it can be relevant here.
