In this second episode of “Philosophy for All,” we analyse what a sign is and its difference from a symbol. Both sign and symbol point us to a reality beyond themselves. The sign and the symbol, without which we cannot live, are not the reality they point us to. Paul Ricœur (1913–2005), a French Philosopher, tells us that idolatry occurs when a symbol is mistaken for the reality. Idolatry, we can add, can also occur when the reality is mistaken for the symbol and everything becomes merely symbolic.
