A few quotes from 'Leviathan'

I was reading some thing about Thomas Hobbes the other day and I came across some quotes from 'Leviathan'. I have reproduced the ones I liked best. "Another doctrine repugnant to civil society, is that whatsoever a man does against his conscience, is sin; and it dependeth on the presumption of making himself judge of good and evil. For a man's conscience and his judgement are the same thing, and as the judgement, so also the conscience may be erroneous." "...in the first place, I put for a general inclination of all mankind, a perpetual and restless desire of power after power, that ceaseth only in death." "Man gives indifferent names to one and the same thing from the difference of their own passions; as they that approve a private opinion call it opinion; but they that mislike it, heresy: and yet heresy signifies no more than private opinion."
