“He who does not see the vanity of the world is himself very vain. Indeed who do not see it but youths who are absorbed in fame, diversion, and the thought of the future? But take away diversion, and you will see them dried up with weariness. They feel then their nothingness without knowing it; for it is indeed to be unhappy to be in insufferable sadness as soon as we are reduced to thinking of self, and have no diversion.” If our condition were truly happy, we would not need diversion from thinking of it in order to make ourselves happy. As men are not able to fight against death, misery, ignorance, they have taken it into their heads, in order to be happy, not to think of them at all. The only thing which consoles us for our miseries is diversion, and yet this it the greatest of our miseries. For it is this which principally hinders us from reflecting upon ourselves, and which makes us insensibly ruin ourselves. Without this we should be in a state of weariness, and this weariness would spur us to seek a more solid means of escaping from it. But diversion amuses us, and leads us unconsciously to death”
Among the contemporaries of Descartes none displayed greater natural genius than Pascal, but his mathematical reputation rests more on what he might have done than on what he actually effected, as during a considerable part of his life he deemed it his duty to devote his whole time to religious exercises.
At 16, Pascal began designing a calculating machine, which he finally perfected when he was thirty, the pascaline, a beautiful handcrafted box about fourteen by five by three inches. The first accurate mechanical calculator was born.
Pascal was dismayed and disgusted by society's reactions to his machine and completely renounced his interest in science an mathematics, devoting the rest of his life to God. He is best known for his collection of spiritual essays, Les Pensees.
Ironically, Pascal, who was a genius by any measure, with one of the finest brains of all time, died of a brain hemorrhage at the age of 39.

He was a child prodigy who was educated by his father, a Tax Collector in Rouen. Pascal's earliest work was in the natural and applied sciences where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalizing the work of Evangelista Torricelli.
In 1646, he and his sister Jacqueline identified with the religious movement within Catholicism known by its detractors as Jansenism. Following a mystical experience in late 1654, he had his "second conversion", abandoned his scientific work, and devoted himself to philosophy and theology. His two most famous works date from this period: the Lettres provinciales and the Pensees.
In honor of his scientific contributions, the name Pascal has been given to the SI unit of pressure, to a programming language, and Pascal's law (an important principle of hydrostatics), and as mentioned above, Pascal's triangle and Pascal's wager still bear his name.
