"Cynicism originates in the philosophical schools of ancient Greece that claim a Socratic lineage. To call the Cynics a “school” though, immediately raises a difficulty for so unconventional and anti-theoretical a group. Their primary interests are ethical, but they conceive of ethics more as a way of living than as a doctrine in need of explication. As such askēsis—a Greek word meaning a kind of training of the self or practice—is fundamental. The Cynics, as well as the Stoics who followed them, characterize the Cynic way of life as a “shortcut to virtue” (see Diogenes Laertius, Lives of Eminent Philosophers, Book 6, Chapter 104 and Book 7, Chapter 122). Though they often suggest that they have discovered the quickest, and perhaps surest, path to the virtuous life, they recognize the difficulty of this route.
The colorfulness of the Cynic way of life presents certain problems. The triumph of the Cynic as a philosophical and literary character complicates discussions of the historical individuals, a complication further troubled by a lack of sources. The evidence regarding the Cynics is limited to apothegms, aphorisms, and ancient hearsay; none of the many Cynic texts have survived. The tradition records the tenets of Cynicism via their lives. It is through their practices, the selves and lives that they cultivated, that we come to know the particular Cynic ēthos."
"Known in antiquity as an accomplished orator, a companion of Socrates, and a philosopher, Antisthenes presently gains renown from his status as either a founder or a forerunner of Cynicism. He was the teacher to Diogenes of Sinope, and he is regarded by Diogenes Laertius as the first Cynic philosopher. He is credited with the authorship of over sixty titles, appears as one of the primary interlocutors in Xenophon’s Memorabilia and Symposium, and is mentioned as one of those present at Socrates’ death by Plato, with whom it seems he had a falling out. Antisthenes’ philosophical interests engage ethics rather than metaphysics or epistemology, and he advocates the practice of virtue through an ascetic life and the cultivation of wisdom. Like Socrates before him, Antisthenes adheres to ethical intellectualism, and like the Stoics who follow the Cynics, he claims that virtue is sufficient for happiness."
"The most illustrious of the Cynic philosophers, Diogenes of Sinope serves as the template for the Cynic sage in antiquity. An alleged student of Antisthenes, Diogenes maintains his teacher’s asceticism and emphasis on ethics, but brings to these philosophical positions a dynamism and sense of humor unrivaled in the history of philosophy. Though originally from Sinope, the majority of the stories comprising his philosophical biography occur in Athens, and some of the most celebrated of these place Alexander the Great or Plato as his foil.It is disputed whether Diogenes left anything in writing. If he did, the texts he composed have since been lost. In Cynicism, living and writing are two components of ethical practice, but Diogenes is much like Socrates and even Plato in his sentiments regarding the superiority of direct verbal interaction over the written account. Diogenes scolds Hegesias after he asks to be lent one of Diogenes’ writing tablets: “You are a simpleton, Hegesias; you do not choose painted figs, but real ones; and yet you pass over the true training and would apply yourself to written rules” (Diogenes Laertius, Lives of Eminent Philosophers, Book 6, Chapter 48). In reconstructing Diogenes’ ethical model, then, the life he lived is as much his philosophical work as any texts he may have composed."
"Hipparchia is notable for being one of the few women philosophers of Ancient Greece. Drawn to the doctrines and the self-imposed hardships of the Cynic lifestyle, Hipparchia lived in poverty with her husband, Crates the Cynic. While no existing writings are directly attributed to Hipparchia, recorded anecdotal accounts emphasize both her direct, Cynic rhetoric and her nonconformity to traditional gendered roles. Entering into marriage is a traditional social role that Cynics would normally reject; yet with her marriage to Crates, Hipparchia raised Greek cultural expectations regarding the role of women in marriage, as well as the Cynic doctrine itself. With her husband, Hipparchia publicly embodied fundamental Cynic principles, specifically that the path toward virtue was the result of rational actors living in accordance with a natural law that eschewed conventional materialism and embraced both self-sufficiency and mental asperity. Written accounts of Hipparchia’s life reference in particular both her belief in human shamelessness or anaideia, and her rhetorical acuity at Greek symposiums traditionally attended only by men. Along with Crates, Hipparchia is considered a direct influence on the later school of Stoicism."
