“All men seek happiness. This is without exception. Whatever different means they employ, they all tend to this end. The cause of some going to war, and of others avoiding it, is the same desire in both, attended with different views. The will never takes the least step but to this object. This is the motive of every action of every man, even of those who hang themselves. And yet after such a great number of years, no one without faith has reached the point to which all continually look. All complain, princes and subjects, noblemen and commoners, old and young, strong and weak, learned and ignorant, healthy and sick, of all countries, all time, all ages, and all conditions. A trial so long, so continuous, and so uniform should certainly convince us of our inability to reach the good by our own efforts.... What is it then that this desire and this inability proclaim to us, but that there was once in man a true happiness of which there now remains to him only; the mark and empty trace, which he in vain tries to fill from all his surroundings, seeking from things absent the help he does not obtain in things present? But these are all inadequate, because the infinite abyss can only be filled by an infinite and immutable Object, that is to say, only by God Himself.”
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.
