Tourette syndrome or Tourette's syndrome (abbreviated as TS or Tourette's) is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements. These are typically preceded by an unwanted urge or sensation in the affected muscles known as a premonitory urge, can sometimes be suppressed temporarily, and characteristically change in location, strength, and frequency. Tourette's is at the more severe end of a spectrum of tic disorders. The tics often go unnoticed by casual observers.

Tourette's was once regarded as a rare and bizarre syndrome and has popularly been associated with coprolalia (the utterance of obscene words or socially inappropriate and derogatory remarks). It is no longer considered rare; about 1% of school-age children and adolescents are estimated to have Tourette's, though coprolalia occurs only in a minority. There are no specific tests for diagnosing Tourette's; it is not always correctly identified, because most cases are mild, and the severity of tics decreases for most children as they pass through adolescence. Therefore, many go undiagnosed or may never seek medical attention. Extreme Tourette's in adulthood, though sensationalized in the media, is rare, but for a small minority, severely debilitating tics can persist into adulthood. Tourette's does not affect intelligence or life expectancy. (Full article...)

• "Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality." — Jean Piaget

John Dewey (/ˈduːi/; October 20, 1859 – June 1, 1952) was an American philosopher, psychologist, and educational reformer. He was one of the most prominent American scholars in the first half of the twentieth century.

The overriding theme of Dewey's works was his profound belief in democracy, be it in politics, education, or communication and journalism. As Dewey himself stated in 1888, while still at the University of Michigan, "Democracy and the one, ultimate, ethical ideal of humanity are to my mind synonymous." Dewey considered two fundamental elements—schools and civil society—to be major topics needing attention and reconstruction to encourage experimental intelligence and plurality. He asserted that complete democracy was to be obtained not just by extending voting rights but also by ensuring that there exists a fully formed public opinion, accomplished by communication among citizens, experts and politicians.
