Classical Virtues in Python

September 2025

Growing up in a Calvinist household and attending a fundamental Southern Baptist Christian school through middle school gave me deep exposure to virtue-based thinking. While my relationship with institutional religion has evolved, the emphasis on character formation left a lasting impression. The classical seven virtues—four cardinal virtues from ancient philosophy and three theological virtues from Christian tradition—provide a framework for human flourishing that transcends any single religious system.

As I explored in Ram Dass Teachings in Python and Vedic Principles in Python, wisdom traditions across cultures identify similar patterns for character development. The classical virtues represent Western civilization's distillation of these patterns into systematic form—practical algorithms for living well.

Our increasingly disconnected digital age desperately needs these foundational virtues. Below are the seven classical virtues translated into Python—not to reduce the profound to the technical, but to reveal timeless patterns through contemporary metaphors.

The Cardinal Virtues: Ancient Wisdom

The four cardinal virtues come from ancient Greek and Roman philosophy—Plato, Aristotle, and the Stoics identified these as the "hinges" (cardines) upon which all other virtues turn.

Prudence: Practical Wisdom

Prudentia - The Master Virtue

Prudence governs the other virtues by providing practical wisdom about right action in specific circumstances:

from dataclasses import dataclass
from typing import Any, List, Optional

@dataclass
class Prudence:
    """Practical wisdom - the charioteer of the virtues."""
    experience: List[Any]
    reflection: callable
    good_judgment: bool = True
    
    def deliberate(self, situation: Any) -> Any:
        """Consider all relevant factors before acting."""
        
        # Gather information
        facts = self.examine_circumstances(situation)
        consequences = self.predict_outcomes(situation)
        principles = self.apply_universal_truths(situation)
        
        # Synthesize wisdom
        past_learning = self.consult_experience(self.experience)
        present_context = self.assess_current_reality(situation)
        future_impact = self.consider_long_term_effects(consequences)
        
        return self.choose_wisely(facts, principles, past_learning, present_context, future_impact)
    
    def know_thyself(self) -> dict:
        """Self-knowledge as foundation of wisdom."""
        return {
            'strengths': self.honest_assessment_of_capabilities(),
            'weaknesses': self.acknowledge_limitations(),
            'biases': self.recognize_cognitive_distortions(),
            'values': self.clarify_core_principles()
        }
    
    def discern_timing(self, action: Any) -> bool:
        """Knowing when to act and when to wait."""
        if self.conditions_are_right(action) and self.resources_available(action):
            return True
        return False

Prudence serves as the operating system for ethical decision-making—without it, other virtues become rigid rules rather than flexible wisdomThomas Aquinas called prudence "auriga virtutum" (the charioteer of the virtues) because it directs how all other virtues should be applied in specific situations..

Justice: Right Relationships

Justitia - Giving Each Their Due

Justice ensures proper relationships between individuals and within communities:

@dataclass
class Justice:
    """Giving to each what they are owed."""
    
    def render_what_is_owed(self, person: Any, context: Any) -> Any:
        """The fundamental algorithm of justice."""
        
        debt = self.calculate_what_is_owed(person, context)
        
        if debt.type == "distributive":
            # Fair allocation of resources/burdens
            return self.distribute_proportionally(debt)
            
        elif debt.type == "corrective":
            # Restoring balance after wrongdoing
            return self.restore_equilibrium(debt)
            
        elif debt.type == "commutative":
            # Fair exchange between equals
            return self.ensure_equal_exchange(debt)
    
    def uphold_rights(self, community: List[Any]) -> None:
        """Protect legitimate claims of all members."""
        
        for person in community:
            basic_rights = person.get_human_dignity_rights()
            earned_rights = person.get_merit_based_rights()
            
            self.protect_rights(basic_rights)
            self.honor_earned_rights(earned_rights)
    
    def establish_rule_of_law(self, society: Any) -> dict:
        """Systems that apply principles consistently."""
        
        return {
            'equal_treatment': self.apply_same_standards_to_all(),
            'due_process': self.ensure_fair_procedures(),
            'proportional_response': self.match_consequences_to_actions(),
            'impartial_judgment': self.remove_personal_bias()
        }

Justice creates the framework within which all other virtues can flourish—without fair systems, individual virtue becomes meaningless in social contextsAristotle distinguished between distributive justice (fair allocation), corrective justice (addressing wrongs), and commutative justice (fair exchange)—categories still used in legal philosophy today..

Fortitude: Courage Under Pressure

Fortitudo - Strength in Adversity

Fortitude enables us to pursue good even when facing opposition, difficulty, or danger:

@dataclass
class Fortitude:
    """Courage to do right despite opposition."""
    
    def face_adversity(self, challenge: Any) -> Any:
        """Stand firm when doing right is difficult."""
        
        if challenge.threatens_safety():
            physical_courage = self.act_despite_bodily_harm()
            return physical_courage.proceed_with_caution()
            
        elif challenge.threatens_reputation():
            moral_courage = self.act_despite_social_consequences()
            return moral_courage.speak_truth_anyway()
            
        elif challenge.threatens_comfort():
            spiritual_courage = self.act_despite_personal_cost()
            return spiritual_courage.sacrifice_for_greater_good()
    
    def endure_suffering(self, hardship: Any) -> str:
        """Patience under trial without losing hope."""
        
        while hardship.persists():
            # Maintain dignity and purpose
            self.refuse_to_compromise_principles()
            self.find_meaning_in_suffering()
            self.support_others_in_similar_trials()
            
        return "Character refined through fire"
    
    def take_calculated_risks(self, opportunity: Any) -> bool:
        """Courage is not absence of fear but right action despite it."""
        
        if self.prudence.deems_worthy(opportunity):
            fear_level = self.assess_legitimate_concerns(opportunity)
            potential_good = self.evaluate_benefits(opportunity)
            
            if potential_good > fear_level:
                return self.act_courageously()
                
        return self.wait_for_better_opportunity()

Fortitude bridges the gap between knowing what's right and actually doing it—courage transforms moral knowledge into moral actionC.S. Lewis wrote that courage is not simply one of the virtues, but the form of every virtue at the testing point—you cannot practice any virtue consistently without courage..

Temperance: Self-Regulation

Temperantia - Moderation and Self-Control

Temperance governs our relationship with pleasure, ensuring desires serve rather than enslave us:

@dataclass
class Temperance:
    """Self-mastery over appetites and desires."""
    
    def moderate_pleasures(self, desire: Any) -> Any:
        """Enjoy good things without being controlled by them."""
        
        if desire.is_legitimate_good():
            appropriate_amount = self.calculate_proper_portion(desire)
            appropriate_timing = self.determine_right_moment(desire)
            appropriate_context = self.ensure_suitable_setting(desire)
            
            if all([appropriate_amount, appropriate_timing, appropriate_context]):
                return self.enjoy_responsibly(desire)
                
        return self.abstain_wisely(desire)
    
    def develop_self_control(self, impulse: Any) -> str:
        """Freedom through discipline."""
        
        # First, understand the impulse
        root_need = self.identify_underlying_need(impulse)
        trigger_pattern = self.recognize_activation_conditions(impulse)
        
        # Then, create healthy response
        if root_need.is_legitimate():
            healthy_fulfillment = self.find_virtuous_satisfaction(root_need)
            return self.redirect_impulse(impulse, healthy_fulfillment)
        else:
            return self.transform_disordered_desire(impulse)
    
    def practice_delayed_gratification(self, temptation: Any) -> Any:
        """Present discipline for future freedom."""
        
        immediate_pleasure = temptation.short_term_benefit
        future_consequence = temptation.long_term_cost
        
        if future_consequence > immediate_pleasure:
            return self.choose_long_term_good()
        else:
            return self.enjoy_harmless_pleasure()

Temperance creates space for higher pursuits by ensuring lower appetites don't dominate consciousness—freedom from compulsion enables freedom for purposeThe Stoics understood temperance not as joyless asceticism but as the skill of enjoying pleasure without being enslaved by it—mastery rather than suppression..

The Theological Virtues: Divine Gifts

The three theological virtues were added by Christian thinkers as gifts that transcend human capability—they connect finite humans with infinite reality.

Faith: Trust Beyond Evidence

Fides - Confidence in Ultimate Reality

Faith provides foundation for hope and love by establishing trust in what transcends immediate experience:

@dataclass  
class Faith:
    """Trust in realities beyond empirical verification."""
    
    def trust_beyond_proof(self, uncertain_reality: Any) -> bool:
        """Confidence based on sufficient but not conclusive evidence."""
        
        available_evidence = uncertain_reality.gather_supporting_data()
        rational_analysis = uncertain_reality.logical_coherence()
        experiential_confirmation = uncertain_reality.lived_verification()
        authoritative_testimony = uncertain_reality.credible_witnesses()
        
        total_support = sum([available_evidence, rational_analysis, 
                           experiential_confirmation, authoritative_testimony])
        
        if total_support >= self.minimum_threshold_for_reasonable_belief():
            return self.commit_despite_remaining_uncertainty()
        else:
            return self.maintain_healthy_skepticism()
    
    def live_according_to_unseen_realities(self, daily_choices: List[Any]) -> List[Any]:
        """Let invisible truths shape visible actions."""
        
        transformed_choices = []
        for choice in daily_choices:
            if self.eternal_perspective_changes_calculation(choice):
                better_choice = self.choose_based_on_ultimate_reality(choice)
                transformed_choices.append(better_choice)
            else:
                transformed_choices.append(choice)  # Some choices are morally neutral
                
        return transformed_choices
    
    def maintain_trust_through_difficulty(self, trial: Any) -> str:
        """Faith tested becomes faith strengthened."""
        
        if trial.challenges_belief():
            deeper_understanding = self.wrestle_with_questions(trial)
            refined_trust = self.emerge_with_mature_faith(deeper_understanding)
            return refined_trust
        else:
            return self.continue_trusting()

Faith doesn't eliminate reason but transcends its limitations—providing foundation for commitments that evidence alone cannot fully justifyAquinas argued that faith and reason are complementary rather than contradictory—faith accepts truths beyond reason's reach but not against reason's findings..

Hope: Confident Expectation

Spes - Trust in Ultimate Good

Hope sustains effort toward goals that may not be achieved in this lifetime:

@dataclass
class Hope:
    """Confident expectation of ultimate good."""
    
    def maintain_vision(self, setback: Any) -> Any:
        """Keep sight of the goal despite temporary defeats."""
        
        if setback.seems_permanent():
            longer_perspective = self.expand_time_horizon(setback)
            return self.trust_in_eventual_vindication(longer_perspective)
            
        elif setback.seems_insurmountable():
            alternative_paths = self.find_different_routes_to_goal(setback)
            return self.adapt_strategy_while_keeping_destination(alternative_paths)
            
        else:
            return self.persevere_through_temporary_difficulty(setback)
    
    def inspire_others(self, community: List[Any]) -> List[Any]:
        """Hope is contagious when genuine."""
        
        hopeful_community = []
        for person in community:
            if person.is_discouraged():
                shared_vision = self.communicate_realistic_optimism(person)
                renewed_person = person.receive_hope(shared_vision)
                hopeful_community.append(renewed_person)
            else:
                hopeful_community.append(person)
                
        return hopeful_community
    
    def transform_suffering(self, pain: Any) -> Any:
        """Hope doesn't eliminate suffering but gives it meaning."""
        
        if pain.serves_greater_purpose():
            meaningful_suffering = self.find_redemptive_value(pain)
            return meaningful_suffering.bear_with_purpose()
        else:
            return self.work_to_eliminate_pointless_suffering(pain)

Hope prevents despair by maintaining confidence that present struggles serve ultimate purpose—it's optimism grounded in conviction about reality's fundamental natureHope differs from mere optimism by being anchored in metaphysical convictions about reality's ultimate structure rather than temperamental disposition or wishful thinking..

Love: Self-Transcending Care

Caritas - Love That Seeks the Good of Others

Love completes the virtues by providing their ultimate motivation—the good of others rather than merely self-improvement:

@dataclass
class Love:
    """Willing the good of another for their own sake."""
    
    def seek_others_good(self, person: Any) -> Any:
        """Love as choice rather than feeling."""
        
        their_authentic_good = self.discern_what_truly_benefits(person)
        my_emotional_state = self.current_feelings_toward(person)
        
        # Love acts regardless of emotional state
        if their_authentic_good.requires_action():
            return self.choose_their_benefit_over_my_comfort(their_authentic_good)
        else:
            return self.respect_their_autonomy()
    
    def practice_self_sacrifice(self, loved_ones: List[Any], self_interest: Any) -> Any:
        """Love gives rather than takes."""
        
        legitimate_needs_of_others = sum([person.essential_needs() for person in loved_ones])
        my_legitimate_needs = self_interest.essential_needs()
        
        if legitimate_needs_of_others > my_legitimate_needs:
            return self.give_preferentially_to_others()
        else:
            return self.maintain_healthy_self_care()  # Can't give what you don't have
    
    def love_enemies(self, opponent: Any) -> Any:
        """The highest expression of love."""
        
        if opponent.has_wronged_me():
            # Forgiveness doesn't mean enabling harmful behavior
            appropriate_boundaries = self.establish_protective_limits(opponent)
            genuine_care = self.wish_their_authentic_transformation(opponent)
            
            return self.combine_boundaries_with_care(appropriate_boundaries, genuine_care)
        else:
            return self.treat_as_fellow_human_being(opponent)
    
    def integrate_all_virtues(self, moral_situation: Any) -> Any:
        """Love provides the why for all other virtues."""
        
        prudent_analysis = Prudence().deliberate(moral_situation)
        just_distribution = Justice().render_what_is_owed(moral_situation)
        courageous_action = Fortitude().face_adversity(moral_situation)
        temperate_moderation = Temperance().moderate_pleasures(moral_situation)
        faithful_trust = Faith().trust_beyond_proof(moral_situation)
        hopeful_perseverance = Hope().maintain_vision(moral_situation)
        
        # Love motivates and harmonizes all other virtues
        return self.unite_virtues_in_service_of_good(
            prudent_analysis, just_distribution, courageous_action,
            temperate_moderation, faithful_trust, hopeful_perseverance
        )

Love serves as the form and purpose of all other virtues—without love, virtues become self-serving excellence rather than genuine goodnessAs St. Paul wrote in 1 Corinthians 13, without love, even the most impressive virtuous actions become "sounding brass or tinkling cymbal"—impressive but ultimately empty..

Integration: The Virtue Operating System

The seven classical virtues work together as an integrated system for human flourishing:

class VirtuousLife:
    """The complete virtue stack."""
    
    def __init__(self):
        # Cardinal virtues - natural human excellence
        self.prudence = Prudence()
        self.justice = Justice()  
        self.fortitude = Fortitude()
        self.temperance = Temperance()
        
        # Theological virtues - divine gifts
        self.faith = Faith()
        self.hope = Hope()
        self.love = Love()
    
    def live_virtuously(self, situation: Any) -> Any:
        """Integrated virtue response."""
        
        # Prudence evaluates the situation
        wise_assessment = self.prudence.deliberate(situation)
        
        # Justice determines what's owed
        fair_response = self.justice.render_what_is_owed(situation)
        
        # Fortitude provides courage to act
        courageous_execution = self.fortitude.face_adversity(fair_response)
        
        # Temperance ensures moderation
        temperate_action = self.temperance.moderate_pleasures(courageous_execution)
        
        # Faith grounds action in ultimate reality
        faithful_commitment = self.faith.trust_beyond_proof(temperate_action)
        
        # Hope sustains long-term effort
        hopeful_perseverance = self.hope.maintain_vision(faithful_commitment)
        
        # Love provides the motivation and form
        loving_completion = self.love.seek_others_good(hopeful_perseverance)
        
        return loving_completion

def main():
    """The program of human flourishing."""
    
    virtuous_person = VirtuousLife()
    
    while life.continues():
        current_situation = life.present_challenge()
        virtuous_response = virtuous_person.live_virtuously(current_situation)
        
        # Virtue creates more virtue
        character = character.strengthen_through_practice(virtuous_response)
        community = community.improve_through_good_example(virtuous_response)
        
    return "A life well lived"

if __name__ == "__main__":
    main()

Why These Virtues Matter Now

Growing up with virtue-based formation created appreciation for character that purely secular frameworks struggle to motivate. The classical virtues offer several advantages over modern approaches to ethics:

Systematic Integration: Rather than isolated rules, virtues work together as a coherent system for human development.

Practical Wisdom: Prudence provides the flexibility that rigid moral codes lack—virtue adapts to circumstances while maintaining core principles.

Character Formation: Virtues focus on becoming the kind of person who naturally acts well, rather than just following external rules.

Transcendent Purpose: The theological virtues connect individual flourishing with ultimate meaning and community good.

Time-Tested Durability: These patterns have guided human development across cultures and centuries because they align with how humans actually flourish.

Our digital age desperately needs this foundation. As I explored in The Algorithm Eats Virtue, social media algorithms optimize for engagement over virtue. Political discourse rewards tribal loyalty over justice. Economic systems prioritize efficiency over human dignity. The classical virtues provide stable ground for building lives and communities that serve human flourishing rather than exploit human weakness.

The pseudo-Python is metaphor. The character it describes is what we need to cultivate in ourselves and our institutions.
