## Study Notes

### True or False Statements

• Statements lacking a way to determine truth are considered neither true nor false, which is false.
• A person's sincere belief does not determine the truth of a statement; this is false.
• Again, if there is uncertainty, the statement is neither true nor false; this is false.
• The belief of a majority does not make a statement true; therefore, this claim is false.
• Different individuals cannot hold differing truths about a statement, marking this statement as false.

### Truth Values of Statements

• Every genuine statement must be categorized as either true or false; this is true.
• A statement cannot simultaneously be both true and false; this claim is false.
• Determining the truth of a statement relies solely on the statement's content and its alignment with facts; this is true.

### Validity and Arguments

• Not all valid arguments necessarily have true conclusions; this statement is false.
• Conversely, some valid arguments can indeed have false conclusions; this is also false.
• Arguments do not require a strict structure of two premises and one conclusion, making this claim false.
• Although circular arguments can be considered valid, they are not typically strong; this is true.

### Cogency and Soundness

• A cogent argument cannot be sound, signifying this statement as false.
• Deductive reasoning does not rely on patterns of cogent arguments, thus this statement is false.
• Inductive reasoning does not use valid argument patterns, which denotes this claim as false.
• True premises combined with a true conclusion do not guarantee validity, highlighting this as false.
• An argument can yield false conclusions despite having all false premises, making this statement false.
• Validity can exist even if an argument has all true premises and a false conclusion; this is false.

### Relationship Between Validity and Truth

• It is indeed possible to have a cogent argument with true premises but a false conclusion, which is true.
• A valid argument with a false conclusion necessitates at least one false premise; this claim is true.
• Valid arguments can have true conclusions without all premises being true, signifying this statement as false.
• Arguments can be both valid and cogent simultaneously; this assertion is false.
• All cogent arguments are categorized as invalid; this statement is true.

### Forms of Argument

• Not all invalid arguments are poorly structured, validating this claim as false.
• However, it is true that all ill-formed arguments are classified as invalid.
• Strong arguments do not necessarily contain true premises; hence, this statement is false.
• Similarly, not all strong arguments can be deemed valid; this claim is false.
• Finally, it is false that no strong arguments possess false premises.
