Nothing has been as instructive in exploring the notion of authenticity as relearning the work of the great philosophers Aristotle and Plato. We are struck by their applicability to our work as we help companies and people develop their brands. Why do these early philosophers have so much to say that is helpful to modern marketers? We believe it is because they were focused on the fundamental issues of authenticity that we all face: Who are we? Why are we? How should we behave? Asking these questions encourages us to deepen our self-awareness. In particular, this issue of “who are we?” is critical. Knowing who we are is the key to elevating our capacities and performance.
