Just as in all expressions of the intellectual life of the Greek people, it is evident that alongside the ancient tradition there is also a newer creation worthy of the ancient one, born out of the same exact needs. These prejudices are characteristic of the mentality of the people and reflect their moral and intellectual forces.
With this book, the aim is not to identify or compare today's prejudices with similar or analogous ancient ones, nor to distinguish the common ones from those prejudices that are found individually in certain places. It also does not seek to determine the places where each of the non-common prejudices are found. It simply refers to the main current prejudices that prevailed in various places in Greece, accompanied by an attempt at a brief interpretation of their formation, where possible.
