What is the connection between Lady Macbeth and the Witches in Shakespeare's Macbeth?

Shakespeare did not merely "refer" to philosophy; he weaponized the radical uncertainty of the late Renaissance to dismantle the medieval certainties of his audience. Rather than offering a coherent system of thought, his plays serve as a laboratory where competing contemporary frameworks—from the ruthless pragmatism of Machiavelli to the profound skepticism of Montaigne—are forced into violent collision. ## The Skeptical Turn: Montaigne and Pyrrhonism One of the most profound influences on Shakespeare’s middle and late periods was the revival of [Pyrrhonism](https://plato.stanford.edu/entries/skepticism-ancient/#PyrrSkep), a school of ancient Greek skepticism that suggested human reason is fundamentally incapable of attaining absolute truth. This influence is most visible through Shakespeare’s engagement with Michel de Montaigne’s *Essays*, translated into English by John Florio in 1603. In *Hamlet*, Shakespeare explores the paralysis that results from this skeptical crisis. When the prince famously remarks: > "There is nothing either good or bad, but thinking makes it so." (Hamlet, Act 2, Scene 2) He is not just expressing a personal mood; he is articulating a cornerstone of skeptical thought: that external reality is inaccessible, and we are trapped within our own subjective perceptions. This challenged the traditional Aristotelian view that the universe possessed an inherent, objective moral order. ## Machiavellianism and the Death of Divine Right While the Tudor state officially condemned [Niccolò Machiavelli](https://plato.stanford.edu/entries/machiavelli/), Shakespeare used the stage to explore the Florentine’s provocative ideas regarding *virtù*—the skill and vigor of a leader—independent of Christian morality. Shakespeare’s "Machiavels," such as Richard III or Edmund in *King Lear*, represent a shift from the medieval "Mirror for Magistrates" tradition toward a modern political realism. These characters reject the "Great Chain of Being," arguing that power is not a divine gift but a prize for the most strategically capable. This creates a productive tension between the old world of legitimate bloodlines and the new world of meritocratic, albeit ruthless, ambition. ## Neo-Stoicism and the Roman Plays In his Roman tragedies, Shakespeare draws heavily on **Neo-Stoicism**, a movement led by thinkers like [Justus Lipsius](https://plato.stanford.edu/entries/justus-lipsius/) that sought to reconcile ancient Stoic ethics with Christian doctrine. This philosophy emphasized *constantia* (steadfastness) and the suppression of emotion in the face of fate. In *Julius Caesar*, Brutus serves as a case study in the limits of this philosophy. His attempt to remain emotionally detached from his own actions leads to a psychological fragmentation that Shakespeare uses to critique the Stoic ideal. By placing these "ideal" philosophers in messy, political realities, Shakespeare asks: 1. Can a human truly transcend emotion through reason? 2. Does a philosophical commitment to "virtue" make one more vulnerable to those who play by Machiavellian rules? 3. Is "constancy" a strength, or merely a form of intellectual rigidity? By refusing to provide easy answers, Shakespeare transformed the theater into a space for **dialectic**, forcing his audience to inhabit the tension between these shifting worldviews.
