Any error is harmful, it's for having deceived the human race visited unhappy. Without knowing the nature of the gods were formed, which became the sole object of his hopes and fears. The men have not felt this nature, devoid of goodness as evil, merely follow the necessary and immutable laws by producing and destroying things, making people suffer and sometimes she made sensitive by distributing good and evil, by altering constantly: they have not seen it in nature itself and its own forces that man should seek his needs, remedies against his sentence and means to make them happy, they have wait a few things these imaginary beings they are supposed authors of their pleasures and their misfortunes. Hence we see that it is the ignorance of nature that are due these unknown powers, under which mankind so long trembled, and the superstitious cults that were the source of all evils.
This lack of knowledge of his own nature, its own pattern, its needs and rights as men in society has fallen of freedom in slavery. He thought he mistook or forced to stifle the desires of his heart, and sacrifice his welfare to the whims of its leaders, he ignored the purpose of the association and the government, he submitted unreservedly to men like him , that his prejudices made him look as beings of a higher order, as gods on earth, they took advantage of his mistake to enslave, corrupt, make vicious and miserable.
So it is for ignoring its own nature as the human race fell into bondage and was poorly governed.
