I created Stoic Penknife based on my reading of the French ancient historian and philosopher Pierre Hadot ("What is Ancient Philosophy?", "The Inner Citadel") and Martha Nussbaum's work, above all "The Therapy of Desire" on the ancient Hellenistic schools of philosophy. Both writers have inspired a number of recent works, including Ryan Holiday's 2014 book, "The Obstacle is the Way."
