Ancient Greece (350 BCE)
Aristotle formalizes the three appeals in "Rhetoric"
Ethos, Pathos & Logos in Classical Rhetoric
Rooted in Aristotelian rhetoric, these three appeals form the rhetorical triangle—a timeless framework for effective persuasion across all media.
- Ethos: Speaker credibility and character (who speaks)
- Pathos: Audience emotions and values (who listens)
- Logos: Message structure and reasoning (what is said)

Ethos, pathos, and logos are core elements of classical rhetoric and the rhetorical triangle. Formalized by Aristotle over 2,000 years ago, these appeals remain central to modern writing, marketing, design, and all forms of persuasive communication.
Classical Origins
Aristotle identified ethos, pathos, and logos in his work "Rhetoric" around 350 BCE. These three modes of persuasion formed the foundation of classical rhetoric and have influenced communication theory ever since.
Roman Era
Cicero and Quintilian expand rhetorical theory
Renaissance
Classical rhetoric revived in European education
Modern Era
Applied to advertising, marketing, and design
The Rhetorical Triangle
The rhetorical triangle represents the relationship between speaker (ethos), audience (pathos), and message (logos). Effective persuasion balances all three points.
Speaker (Ethos)
The credibility and character of the communicator
Who is speaking?
Audience (Pathos)
The emotions and values of the listeners
Who is listening?
Message (Logos)
The logical content and reasoning
What is being said?
Modern Applications
How classical rhetoric applies today
Marketing & Advertising
Brands use ethos (trust), pathos (emotion), and logos (benefits) to persuade consumers.
Public Speaking
Speakers establish credibility, connect emotionally, and present logical arguments.
Writing & Content
Writers balance authority, emotional resonance, and clear reasoning.
Design & Branding
Visual identity communicates credibility, emotion, and clarity through design choices.
Digital Communication
Social media, websites, and apps apply rhetorical principles to user experience.
How This Maps to Brand Design
The rhetorical triangle translates directly to modern brand identity
Speaker (Ethos)
→↓Brand Identity
Just as a speaker establishes credibility through character and authority, your brand identity communicates trustworthiness through consistent visual language, professional execution, and authentic representation.
Audience (Pathos)
→↓User Experience
The audience's emotions and values in rhetoric become user experience in design. Your visual choices must resonate with your audience's feelings, aspirations, and cultural context to create meaningful connections.
Message (Logos)
→↓Visual Communication
The logical structure of an argument translates to clear, purposeful visual communication. Every design element should convey information logically, making your brand's value proposition immediately understandable.
