The effects of this staleness is the same everywhere; it is seen in all drug-taking and dram-drinking and every form of the tendency to increase the dose. Men seek stranger things or more startling obscenities as stimulants to their jaded sense. They seek after mad oriental religions for the same reason. They try to stab their nerves to life… They are walking in their sleep and try to wake themselves up with nightmares.
-G.K. Chesterton
