PHL214 is a three-credit formal logic course at Southern New Hampshire University. The catalog lists it as a campus course, offered as needed.
It describes the study of the fundamental principles of correct and incorrect argument, historical forms of deductive logic, and the significance of language and clear verbalization. Check with SNHU about availability if you are studying online, because the catalog does not list an online offering.
Formal logic differs from most humanities courses. Answers are right or wrong according to rules, so careful, step-by-step practice matters more than essay style.

Key Concepts Explained
Validity and Soundness
An argument is valid when the conclusion must be true if the premises are true. It is sound when it is valid and the premises are actually true. Validity concerns form, not truth.
Valid form (modus ponens): If it rains, the ground is wet. It rains. Therefore the ground is wet.
Invalid form (affirming the consequent): If it rains, the ground is wet. The ground is wet. Therefore it rained. The ground could be wet for another reason.
The Classic Syllogism
A categorical syllogism has two premises and a conclusion built from statements such as "All A are B". Checking validity means asking whether the form guarantees the conclusion.
All philosophers are thinkers. Some students are philosophers. Therefore some students are thinkers. This form is valid.
Truth Tables
For the conditional "if P then Q", the statement is false only when P is true and Q is false. Truth tables make this explicit.
| P | Q | If P then Q |
|---|---|---|
| True | True | True |
| True | False | False |
| False | True | True |
| False | False | True |
Typical Assignments and How to Approach Them
| Task type | What it tests | How to approach it |
|---|---|---|
| Translation exercises | Turning sentences into logical form | Identify the connectives first, then assign letters |
| Validity checks | Testing argument forms | Use truth tables or rules consistently |
| Syllogism analysis | Classic forms | Draw a diagram or list the form before judging |
| Quizzes and tests | Speed and accuracy | Practice timed sets |
Practice Drills That Build Speed
Logic improves with repetition on small problems. Try these short drills in different orders until each feels routine.
| Drill | What to do | Why it helps |
|---|---|---|
| Translate | Turn five everyday sentences into symbols | Builds comfort with connectives |
| Spot the form | Label arguments as valid or invalid forms | Trains pattern recognition |
| Counterexample | Invent a case where premises are true and conclusion false | Proves invalidity |
| Table it | Build a truth table for a compound statement | Makes every case explicit |
| Reword | Rewrite an ambiguous sentence so it is clear | Links to the course's focus on clear language |
Look out for tricky English connectives. "A unless B" and "A only if B" do not mean the same as "if A then B" in every setting, so check how your course text translates them and follow its convention consistently.
When a problem fails, find the exact line where it breaks. Writing a short note about the error, such as "forgot that a conditional with a false antecedent is true", turns each mistake into a rule you will not forget.
If You Study on Campus
The SNHU catalog lists PHL214 as a campus course offered as needed, so planning matters. Check the schedule with your campus early in case it is not offered every term.
- Attend any review sessions and ask for extra practice sets.
- Form a small study group and swap problems to solve.
- Bring your worked attempts, including errors, to office hours.
- Keep a notebook of rules you have learned and reread it before tests.
Showing your working, even for wrong answers, makes it much easier for a tutor to see exactly where your reasoning slipped.
Where Students Get Stuck
- Confusing truth and validity. A valid argument can have false premises.
- Translation errors. "Unless" and "only if" are common traps.
- Skipping steps. Write every step; errors hide in mental shortcuts.
- Treating it like an essay course. Accuracy beats style here.
Study Tips for PHL214
- Practice a little every day instead of in one long session.
- Keep a cheat sheet of valid and invalid forms, with one example each.
- Check each answer by trying to build a counterexample.
- Redo missed problems a few days later.
