Chapter 1. Introducing Critical Thinking and Philosophical Inquiry
Practice Exercises: Chapter 1
Group 1: The Branches of Philosophy
Match each philosophical question with its corresponding branch: Metaphysics, Epistemology, Logic, or Axiology (Ethics/Aesthetics).
-
“What is the nature of the self? Is there a part of me that exists beyond my physical body?”
-
“How do we know the difference between a ‘justified belief’ and a ‘lucky guess’?”
-
“Is it always wrong to tell a lie, or can a lie be justified if it prevents a greater harm?”
-
“What are the specific rules that make an argument valid or invalid?”
-
“Is ‘beauty’ something that exists in the object itself, or is it entirely in the eye of the beholder?”
Group 2: Statements vs. Non-statements
Identify whether each of the following is a Statement (an assertion that can be true or false) or a Non-statement (questions, commands, or exclamations).
-
“Philosophy is the most ancient academic discipline.”
-
“Go to the library and check out a book on Socratic irony.”
-
“What time does the Critical Thinking lecture begin at Green River College?”
-
“Wait, I didn’t mean to delete that file!”

Group 3: Arguments vs. Explanations
Determine if each passage is an Argument (intended to prove that something is the case) or an Explanation (intended to show why/how something is the case).
-

-
“You should eat more vegetables because they provide essential vitamins and minerals for your health.”

-
“I am majoring in Philosophy because I want to develop my ability to think clearly about complex issues.”
Group 4: Identifying Premises and Conclusions
For each argument, identify the Conclusion (the claim being supported) and the Premise(s) (the reasons given for the claim).
-
“Since all men are mortal and Socrates is a man, Socrates is mortal.”
-
“The movie must be good. It received five-star reviews from every major critic.”
-
“It is going to rain today; the sky is dark and the barometer is falling.”
-
“We must increase school funding, for education is the backbone of our economy.”
Group 5: Indicators and Inference
Identify the Indicator Word in each sentence and determine if it is a Conclusion Indicator or a Premise Indicator.
-
“I think, therefore I am.”
-
“Because the ground is wet, it must have rained recently.”
-
“You didn’t study for the exam; consequently, you performed poorly.”
