Study Notes

Logic as a Discipline

Logic involves methods and principles to distinguish correct reasoning from incorrect reasoning.
Acquiring logic skills helps evaluate arguments and differentiate good arguments from poor ones.
Effective reasoning requires analyzing if conclusions follow logically from premises.

Importance of Studying Logic

Studying logic enhances innate communication skills and logical reasoning acumen.
Logical training improves the ability to assess the quality of arguments in discussions.
It differentiates between argumentative and non-argumentative discourse, essential for effective decision-making.

Critical Thinking

Glaser defines critical thinking as an attitude of thoughtful consideration, knowledge of logical methods, and skill in their application.
Critical thinking emphasizes evaluating beliefs in light of supporting evidence and potential implications.
Ennis describes critical thinking as reasonable and reflective thinking aimed at decision-making.

Definitions and Their Types

Definitions can be denotative or ostensive; ostensive definitions involve pointing to examples but have geographic and ambiguity limitations.
Intension and extension are key concepts: intension focuses on meaning (attributes), while extension refers to denoting specific instances.

Definition by Genus and Difference

Definition by genus and difference is a widely applicable approach that enhances understanding of terms by analyzing their attributes.
Such definitions break down broader classes into subclasses, allowing for clearer classification and understanding.
Complex attributes can be analyzed into simpler ones, aiding in logical structuring and communication.
