During the trip he was an intimate of Meresenne, who at the time was at the center of the scintitific circle. That circle include the like of Descartes and Gassendi. His first publication was when he returned titled, Elements of Law and politic. This book showed the theories that he began to evovle for him during this third and final trip. Hobbes fled to France for eleven years because of the fear of getting arrested from his book. He called himself "a man of feminine courage". In France he taught the Prince of Whales, later known as King Charles II, mathematics. While in London he also wrote his most famous book Leviathan. This book should Hobbes views on all the theories and ethical decisions. It was published in 1651, the same year he moved back to England. He moved back because he felt safer now in England then he did in France. In actuality he moved back because his book caused him to fear arrest by the authorties in France. He felt safer in England because of his former pupil took over the throne and Hobbes came into favor with the House of Commons. In 1666 however the house passed a bill to inspect his book Leviathan of charges of atheistic tendencies. This inspection caused Hobbes to burn many of his papers and delayed three publications of future books. His philosical theories were that people could have more then one loyalty and that they could be competing with each other. Mainly he was talking about the loyalty to God. Religion was a big deal back then and he stated that God could have a competing loyalty and that people should decide what is best for them. Loyalty to a person or a king should stop when death could occur to you. He stated that loyalty is a social act and that anything a person does is self-serving. Anything a human being does come full circle and benefits them in a way. A theory that Hobbes had, that I believe was pretty big, was that a person living in a world with moral rules is better off then a person living in a world without them.
