4/22: PHIL 105 - Study Notes on Causal Reasoning and Exam Preparation
Course Evaluation and Announcements
Course evaluation forms are available. Students are encouraged to fill them out as they are important for the instructor's job applications.
An announcement with a link to the evaluations will be sent to students.
Exams
Exams that were not collected previously are available for pickup after class.
Grades for participation and attendance will be inputted into Canvas. The instructor aims to complete this by the end of the day.
Causal Reasoning
Discussion of causal reasoning and its importance in various fields of study.
Core Concepts to Remember: - Sufficient Condition: A condition that guarantees the occurrence of the event (event A is a sufficient condition for event B if A's occurrence guarantees B's occurrence). - Necessary Condition: A condition that must be satisfied for an event to occur (event A is a necessary condition for event B if event B cannot occur without A). - Both Necessary and Sufficient Condition: An event that can cause another event and is needed for the event to occur. - Unrelated Events: Two events that do not influence each other’s occurrence.
Relationship Between Events
For any two events A and B: - A is a sufficient condition for B. - A is a necessary condition for B. - A is both necessary and sufficient for B. - A is not related to B.
When discussing causation in science, it relates to these conditions.
Mills' Method
Mills' method focuses on finding the correlation between events.
Introduction of different methods to determine conditions related to events.
Methods of Agreement
Direct Method of Agreement: Identifies necessary conditions for an event through observed presence of conditions.
Inverse Method of Agreement: Identifies sufficient conditions for an event through observed absence of conditions.
Double Method of Agreement
A combination of the direct and inverse methods.
Example:
- If Condition C is necessary for Event E, then whenever E is present, C must also be present. If C is absent, E must also be absent. - Therefore, Condition C is both necessary and sufficient for Event E.Emphasizes probability in determining the nature of relationships between events.
Example Analysis
Consider conditions A (migraine) and B (rain).
Different scenarios can determine if A is a necessary or sufficient condition for B and vice versa.
Method of Differences
Identifies the cause of an event by recognizing what is different between scenarios.
Example provided relates to clinics and the occurrence of an event affecting patient outcomes.
Limitations of Causal Methods
Methods are most effective when the correct necessary or sufficient conditions are already understood.
Understanding that being run over by a steamroller is a sufficient condition for dying but not a necessary condition.
Emphasizes the relevance of conditions when identifying necessary versus sufficient conditions.
Inductive Logic
Inductive arguments do not maintain probability in the same way as deductive arguments (non-monotonicity).
Future evidence can affect the certainty of inductive conclusions.
Exam Overview
Upcoming exam: May 4 at 8 AM.
Format: Similar to previous exams with multiple choice and open-ended questions, including truth tables and diagramming arguments.
Exam will cover: - Aristotelian logic - Propositional logic - Causal reasoning - Analogical reasoning
Excluded content refers to fallacies.
Study Guide and Review Sessions
A study guide will be posted before Friday.
Review sessions on Friday and the following Monday are planned, with the option for extensive review if students express interest.
Students are encouraged to prepare questions and practice problems for these review sessions.
Problem Sets and Assignments
Homework related to evaluating analog arguments will be assigned, focusing on how changes affect argument strength.
Students can submit questions regarding problem sets and understand specific concepts discussed.
