PHL111: Introduction to Critical Thinking

A study guide to SNHU's PHL111, the introduction to arguments, assumptions and reasoning, applied to real-world cases and contemporary issues.

Updated October 2026 · 5 min read

PHL111 is a three-credit introduction to critical thinking at Southern New Hampshire University, offered online and on campus.

The catalog opens with questions: what makes a good argument, are some beliefs better than others, and why should we believe a certain view? It presents philosophy as practical, a way to solve problems, communicate ideas and uncover truth.

Students challenge assumptions, evaluate arguments from different perspectives and take positions on contemporary issues, using real-world situations and case studies.

The hardest shift is from having opinions to supporting them. Marks go to clear reasoning, not to how strongly you feel.

Key Concepts Explained

Premises and Conclusions

An argument gives reasons (premises) for a claim (the conclusion). The first job is to separate them. Words such as "therefore" and "because" often signal which is which.

Invented illustration: "Our team has missed three deadlines in a row, so we should change how we plan." Conclusion: change planning. Premise: three deadlines were missed. Hidden assumption: missed deadlines come from planning, not from something else. Naming that assumption is the critical move.

Common Fallacies

Charitable Evaluation

State an opposing view in its strongest form before responding. This shows fairness and makes your own position more persuasive.

Typical Assignments and How to Approach Them

Task typeWhat it testsHow to approach it
Argument analysisIdentifying structure and flawsList premises and conclusion, then test each link
Case study responseApplying reasoning to a situationDescribe the facts, name the assumptions, reach a reasoned view
Position paperDefending a view on an issuePresent the strongest objection and reply to it
Discussion postsEngaging with others' reasoningRespond to the argument, not the person

A Repeatable Method for Any Argument

When a prompt hands you a passage or a case, a fixed routine saves time and prevents missed steps. Try this one on every task until it becomes automatic.

StepWhat to doOutput
1. Find the conclusionAsk what the author wants you to acceptOne sentence
2. List the premisesPick out each reason offeredA numbered list
3. Surface assumptionsAsk what must be true for the reasons to workOne or two hidden premises
4. Test the supportCheck evidence, relevance and sufficiencyStrengths and weaknesses
5. Consider other viewsState the best opposing caseA short paragraph
6. JudgeSay how convincing the argument is and whyA reasoned verdict

Because the catalog says the course draws on your own experience, you can also apply the method to situations from work or daily life. Describe the situation briefly, then run the six steps. Your reader should be able to see each step in your writing, even if you do not label them.

Writing a Position Paper on a Contemporary Issue

The catalog says students articulate positions on contemporary issues. A position paper follows a simple arc.

Readers trust writers who show they understand the other side. Avoid loaded language that signals the verdict before the argument.
