  • Aristotle writes: “The market-place for buying and selling should be separate from [the] public square and at a distance from it.”

    Now the “public square” in Aristotle’s day was a place for reason & rhetoric toward truth in all academic & societal disciplines. Given that, we at PX Didactic seek to revive the culture of pure education, as defined by Aristotle.

  • The German Shakespeare, Johann Wolfgang von Goethe, writes:You can easily judge the character of a man by how he treats those who can do nothing for him.” 

    PX Didactic agrees wholeheartedly; and in this case, our work makes us unafraid of said judgments.
