What Is Lincoln-Douglas Debate?

Lincoln-Douglas Debate is a one-on-one debate format that focuses on moral and philosophical questions. It’s named after the famous 1858 debates between Abraham Lincoln and Stephen Douglas during their campaign for the Illinois Senate seat. While their debates centered on slavery and states’ rights, modern LD Debate tackles a broad range of ethical and societal topics.

LD Debate emphasizes value-based arguments, meaning competitors often debate what “ought” to be rather than what “is.” This makes it different from formats like policy debate, which focus on practicality and implementation.

Why Is LD Debate Interesting?

1. Philosophical Depth : LD Debate explores complex ethical questions, making it an intellectual playground for students who enjoy tackling abstract ideas like justice, freedom, and equality. The debates encourage critical thinking and philosophical reasoning.
2. One-on-One Interaction : Unlike team-based debate formats, LD Debate is individual. This creates a personal dynamic where debaters engage directly, making for a more intimate and focused competition.
3. Balanced Approach : LD combines logical reasoning, emotional appeal, and rhetorical skill, requiring participants to master all aspects of persuasion.
4. Practical Skills : Engaging in LD Debate hones a variety of transferable skills, including public speaking, critical analysis, research, and quick thinking.

The Structure of LD Debate

LD Debate follows a specific structure designed to balance argumentation and rebuttal. Here’s how a standard round looks:

Speech/Segment Time Limit Purpose

Affirmative Constructive (AC) 6 minutes The affirmative side presents their case, including value, criterion, and arguments.

Cross-Examination (CX) 3 minutes The negative side questions the affirmative side’s case.

Negative Constructive (NC) 7 minutes The negative side presents their case and refutes the affirmative’s arguments.

Cross-Examination (CX) 3 minutes The affirmative side questions the negative side’s case.

First Affirmative Rebuttal (1AR) 4 minutes The affirmative responds to the negative’s case and defends their own.

Negative Rebuttal (NR) 6 minutes The negative refutes the affirmative and consolidates their arguments.

Second Affirmative Rebuttal 3 minutes The affirmative summarizes the debate and delivers the final persuasive push.

Key Components of an LD Round

• Value: The overarching ethical principle or goal being debated (e.g., justice, equality).
• Criterion: A standard used to weigh or evaluate the value (e.g., maximizing individual rights).
• Contentions: Core arguments that support or oppose the resolution.

Key Features of Lincoln-Douglas Debate

1. The Resolution

LD Debates center on a resolution—a statement that defines the topic of debate. Resolutions are value-oriented and typically begin with phrases like “Resolved: It is morally permissible...” or “Resolved: In a just society...”.

Example resolutions might include:

"Resolved: Civil disobedience is justified in a democracy."

"Resolved: Economic inequality is incompatible with democracy."



2. Philosophical Framework

LD Debaters often draw from philosophy to support their arguments. Common frameworks include:

• Utilitarianism: Maximizing happiness for the greatest number.
• Deontology: Following moral rules regardless of outcomes.
• Social Contract Theory: Analyzing the relationship between individuals and the state.

3. Clash

Effective LD Debate is about direct engagement. Competitors must refute their opponent’s arguments while defending their own. This “clash” is central to the debate.



3. Evidence and Analysis

Although LD is value-driven, debaters still need to provide evidence, such as historical examples, studies, or philosophical texts, to back their claims.



How to Prepare for LD Debate

1. Understand the Resolution

Start by thoroughly analyzing the resolution. Break it down into its key components:

1. What values and principles are at stake?
2. What conflicts or tensions exist within the topic?



2. Build Your Case

Craft an affirmative and negative case. Each case should include:

• Introduction: State the resolution, your value, and criterion.
• Contentions: Provide 2-3 strong arguments with evidence and analysis.
• Conclusion: Summarize your position and its significance.



3. Research Thoroughly

Gather evidence from credible sources. Familiarize yourself with philosophical theories, historical examples, and relevant data.



4. Practice Speaking

LD Debate requires clear and persuasive delivery. Practice speaking within time limits, focusing on articulation, pacing, and confidence.



5. Anticipate Rebuttals

Think critically about potential counterarguments to your case and prepare responses.
