I really like to think.
Not a meditational, navel-gazing sort of thinking, but a get uncomfortable and challenge your assumptions sort of thinking (though I do reserve the right for the occasional navel gaze in moments of contentment or lethargy). The Economist is my read of choice for current events (particularly for politics and world affairs). For their holiday issue this year, they've thrown out some superlative mental floss. For your consideration, start with "Arguing to death", a contemplation of Socrates in today's America.
