In ancient Greece, sophists were a category of teachers who specialized in using the tools of philosophy and rhetoric for the purpose of teaching "arete" — excellence, or virtue — predominantly to any young nobleman seeking public office. In modern usage, sophism, sophist and sophistry are derogatory terms. A latter day sophist would not hesitate to craft a specious argument to appear logical while actually representing a falsehood, or he might use obscure words and complicated sentence constructions in order to intimidate the opponent into agreement out of fear of feeling foolish.

You ain't seen nothin' yet. Khaw Boon Wan has come up with a new math for buying a $100,000 flat on a $1,000/month salary. Specifically, he was enlarging on Finance Minister Tharman Shanmugeratnam mind-boggling declaration in parliament: "98 per cent of Singaporeans below the age of 35 earn at least $1,000 and are able to buy HDB flats". Khaw explained that Tharman was referring to a two-room flat, which has a subsidised price of about $100,000. If the applicant is a first-timer, there is a housing grant of up to $60,000, and the net purchase price will be about $40,000. Ergo, the $100,000 flat can be sold for $40,000 and HDB won't go broke. Khaw only tripped when he revealed that the median income of two-room applicants, based on recent BTO (build-to-order) launches, is at about $1,400 - those earning $1,000 knew better than to try. Khaw is a good guy, he may stretch the truth a wee bit, but he won't lie all the way to the grave. Unlike some people.
