” a tragedy in the world of crow ( on the numbers ) “

A squire was determined to shoot a crow which made its nest in the watch-tower of his estate. Repeatedly he had tried to surprise the bird, but in vain : at the approach of man the crow would leave its nest. From a distant tree it would watchfully wait until the man had left the tower and then return to its nest. One day the squire hit upon a ruse: two men entered the tower, one remained within, the other came out and went on. But the bird was not deceived: it kept away until the man within came out. The experiment was repeated on the sueceeding days with two, three, then four men, yet without success. Finally, five men were sent: as before, all entered the tower, and one remained while the other four came out and went away. Here the crow lost count. Unable to distinguish between four and five it promptly returned to its nest. (Tobias Dantzig, Number, The Language of Science)

 

 

of course the poor crow do not pass an aritmetic test, maybe the crow made an error of calculation, he was distracted by something, but in this case he did a fatal error. another topic is what is the base N in the world of the crow ? anyway i thank the crow and the snail.  they have their place in thinking.

” 250 years ago : rationalists and snails “

 

On may 27, in the morning, I cut off the head to twenty snails. Fifteen day later two of the snails which I cut the head had a new head and I saw them eating his food. They still eating at the moment. I have no doubt that if I cut off the head to a snail after twenty days she has a new head with her fibers, her nerves, her mouth, her eyes etc. Also a boy can cut off the head to a snail but it needs a mature man to explain where had gone the ideas, the sensibility etc. of the decapitated snails? Always we believe the head is the site of the sensibility and of the ideas and the principle of the vitality. The regeneration of the head is the refuting of ten thousands books about Metaphisics since the Greeks… and it is a sincere thanks to snails. The Nature is really a force. I think in a future that the Science could make a new good head to a man that has not one. The philosophers and theologians are like a child, they do not have the reason. The real world is so deep, it is an abyss hence the mankind must bow to the Nature.

(Sigularités de la nature, François-Marie Arouet Voltaire, 1768)
