This science will be attained in fact as soon as we have an analytical knowledge of the elements and a synthetic understanding of their combinations. Thus Hobbes believed that he had saved science as an absolute value, even though such a value is only phenomenal, being an operation of the mind and not an objective contact with external reality. Matter is not passive, as it was for Descartes. On the contrary, it is endowed with motion, and this motion is from within. The intrinsic motion of matter has given origin to the diversity of the inorganic and organic world.
Life is thus a product of matter and motion, and the human soul is a composite of very subtle atoms.
Hobbes does not deny the existence of God, but he is decidedly opposed to any positive revealed religion, including Christianity. Even the moral life does not exceed the limits of matter and of motion. Sensations, passing to the heart, generate pleasure and hate, that is, inclinations and repulsions. Men naturally tend to pleasure considered as a form of self-satisfaction. But such a tendency must be rationalized by calculation, in order that it may bring greater pleasure.
