“, and all that, who did not know the meaning of a ‘flush.’ It is enough ” +
“to make one ashamed of one’s species.”;
fowler.quote = “Any fool can write code that a computer can understand. ” +
“Good programmers write code that humans can understand.”;
poe.quote = “Deep into that darkness peering, long I stood there, wondering, ” +
“fearing, doubting, dreaming dreams no mortal ever dared to dream before.”;
plato.quote = “All things will be produced in superior quantity and quality, and with greater ease, ” +
