Which of the following best describes the relationship between facts and theory according to the text?
Which of the following best describes the relationship between facts and theory according to the text?
- Scientific knowledge is constructed by first establishing facts and then building theories to fit them.
- Facts and theories are developed independently and do not influence each other.
- Theories should be established first, and then facts should be collected to support them.
- The crucial question is the extent to which the theory is supported by the facts, regardless of which comes first. (correct)
In the context of logical reasoning, what does it mean for an argument to be 'valid'?
In the context of logical reasoning, what does it mean for an argument to be 'valid'?
- The argument is widely accepted and aligns with common sense.
- If the premises are true, then the conclusion must also be true. (correct)
- The premises and the conclusion are all true statements.
- The conclusion is likely to be true based on empirical evidence.
Consider the following argument:
- All swans are white.
- This bird is a swan.
- This bird is white.
Assuming the premises are true, what can be said about the conclusion?
Consider the following argument:
- All swans are white.
- This bird is a swan.
- This bird is white.
Assuming the premises are true, what can be said about the conclusion?
- The conclusion is necessarily true. (correct)
- The conclusion is unrelated to the premises.
- The conclusion is false because not all swans are white.
- The conclusion is likely true but not guaranteed.

Study Notes
- Scientific knowledge is often viewed as originating from facts, but the process of deriving theories from these facts is complex.
- The question is the extent to which a theory is supported by the facts, with the strongest claim being that the theory can be logically derived from the facts.
- This chapter explores whether scientific theories can be logically derived from established facts, considering the nature of logical reasoning.
Logic Basics
- Logic deals with deducing statements from other statements; it focuses on what logically follows from what is given.
- In logic, the primary focus is on the deduction of statements from given premises, examining the consequential relationships between them.
- The aim here is to highlight key aspects of logic using simple examples.
Valid Logical Argument
- A valid logical argument is one where if the premises are true, the conclusion necessarily follows.
Example 1
- Premise 1: All books on philosophy are boring.
- Premise 2: This book is a book on philosophy.
- Conclusion: This book is boring.
- The argument is valid because if premises 1 and 2 are true, conclusion 3 must also be true.
