Montesquieu

There are seve­ral things that govern men : cli­mate, reli­gion, laws, the maxims of the govern­ment, exam­ples of things past, ethos, man­ners, whence a gene­ral spi­rit is for­med that results from them.

To the degree that one of these cau­ses acts with more force in each nation, the others yield to it. Nature and cli­mate almost alone domi­nate sava­ges ; man­ners govern the Chinese ; laws tyran­nize Japan ; the ethos used to set the tone in Lacedæmon ; govern­ment maxims and the ancient ethos set it in Rome.
