Theaetetus

Written by Plato

"Theaetetus" by Plato is a philosophical dialogue written in the early-middle 4th century BCE. Socrates engages the young mathematician Theaetetus in a probing investigation of knowledge itself. Together, they examine three different definitions of what knowledge might be—each seemingly plausible, yet each ultimately unsatisfactory. The dialogue concludes without resolution as Socrates departs to face trial for impiety, leaving the fundamental question unanswered in characteristic Platonic fashion.

A Modest Proposal For preventing the children of poor people in Ireland, from being a burden on their parents or country, and for making them beneficial to the publick

Written by Swift, Jonathan

"A Modest Proposal" by Jonathan Swift is a satirical essay written and published in 1729. The work shockingly suggests that Ireland's poor could solve their economic troubles by selling their children as food to the wealthy. Through sustained irony and deadpan humor, Swift uses this outrageous premise to mock hostile attitudes toward the poor and expose the dehumanizing policies of British colonial rule. The essay remains celebrated for its dark wit and biting social commentary.

A Treatise on Good Works — typographic cover

A Treatise on Good Works

Written by Luther, Martin

"A Treatise on Good Works" by Martin Luther is a theological treatise written in the early 16th century during the Reformation period. The text explores the concept of good works in the Christian faith, arguing against the prevailing notion that only traditional religious practices and rituals are acceptable to God. Instead, Luther posits that true good works are those commanded by God and performed out of faith, thus reshaping the understanding of morality and righteousness within the Church. The opening of the treatise sets the stage for Luther's reflection on his role as a pastor and reformer, emphasizing that his writings were motivated by his duty to guide his congregation toward true spiritual understanding. He details his journey of faith and the intellectual struggles that led to his insistence that genuine good works must arise from faith alone, rather than external adherence to rituals. Luther addresses misconceptions about his teachings, reaffirming that good works should not be equated with self-elected or superficial acts. He introduces the central tenets of his argument, which he plans to elaborate on using the framework of the Ten Commandments, thereby outlining a path for believers to engage in meaningful expressions of faith through their everyday actions.
