When 16th-century French philosopher Descartes fi rst uttered the words ‘je pense, donc je suis’ (‘I think, therefore I am’), could he have known how much impact his proposition would have in the centuries to follow? Translated from the original French to gain wider audience, Descartes’ cogito ergo sum quickly became a staple of Latin studies around the world. His proposition is regarded by many as one of the core foundations of modern philosophy. It certainly serves to remind us that we are all thinking human beings. Scholars offer that cogito is necessary before we can move forward in our lives and lies at the heart of performance improvement. With apologies to Descartes, cogito can be taken a step further – as my addition to his quotation above suggests.
