Thanks be unto thee, O my God, that thou hast called me to this admirable light! Thou, the Supreme Intelligence and the Absolute Life of those numbers and those forces which obey thee in order to people the infinite with inexhaustible creation! Mathematics proves thee, the harmonies of Nature proclaim thee, all forms as they pass by salute thee and adore thee!
Abraham knew thee, Hermes divined thee, Pythagoras calculated thee, Plato, in every dream of his genius, aspired to thee; but only one initiate, only one sage has revealed thee to the children of earth, one alone could say of thee: "I and my Father are one." Glory then be his, since all his glory is thine!
Thou knowest, O my Father, that he who writes these lines has struggled much and suffered much; he has endured poverty, calumny, proscription, prison, the forsaking of those whom he loved: --- and yet never did he find himself unhappy, since truth and justice remained to him for consolation!
Thou alone art holy, O God of true hearts and upright souls, and thou knowest if ever I thought myself pure in thy sight! Like all men I have been the plaything of human passions. At last I conquered them, or rather thou has conquered them in me; and thou hast given me for a rest the deep peace of those who have no goal and no ambition but Thyself.
I love humanity, because men, as far as they are not insensate, are never wicked but through error or through weakness. Their natural disposition is to love good, and it is through that love that thou hast given them as a support in all their trials that they must sooner or later be led back to the worship of justice by the love of truth.
Now let my books go where thy Providence shall send them! If they contain the words of thy wisdom they will be stronger than oblivion. If, on the contrary, they contain only errors, I know at least that my love of justice and of truth will survive them, and that thus immortality cannot fail to treasure the aspirations and wishes of my soul hat thou didst create immortal!
