"It is impossible to underrate human intelligence – beginning with one’s own." ― Henry Adams Topic(s): Intelligence More From Henry Adams "Some day science may have the existence of mankind in power, and the human race can commit suicide by blowing up the world." "Politics are a very unsatisfactory game." "Practical politics consists in ignoring facts." More In Intelligence "As liberty and intelligence have increased the people have more and more revolted against the theological dogmas that contradict common sense and wound the tenderest sensibilities of the soul."― Catharine Beecher "The modern mind is in complete disarray. Knowledge has stretched itself to the point where neither the world nor our intelligence can find any foot-hold. It is a fact that we are suffering from nihilism."― Albert Camus "I can’t see what’s wrong about assuming intelligence in your audience and what’s bad news about being rewarded for assuming that."― Steven Moffat
