That little voice in our head

I RECENTLY attended a conference where the keynote speaker, a renowned academic, talked about science and conscience. One of the slides he showed was a quote from Sophocles, the Greek “tragedian” or playwright (496-406BC) which went: “There is no witness so terrible and no accuser so powerful as conscience which dwells within us.”

In most people, the conscience does play a big part in directing the way we behave.
