📖 1. Philosophy, Science and Religion

★ Must-know

📌 Philosophy, science, and religion all begin with questioning but differ in method: philosophy uses logic, reflection, and argumentation; science uses observation and experimentation; and religion uses belief, religious texts, family, and tradition.

Further detail

📌 Philosophy treats truth as modifiable through reflection and improvement, science treats truth as existing and revisable through experimentation, and religion treats truth as fixed with interpretation that may be more or less fixed.

💡 Memory Hook

Philosophy reasons, science experiments, religion believes.

📖 2. Concepts and Their Classifications

🔑 Key Concepts & Definitions

• Concept : a mental representation that groups ideas and phenomena into a category sharing one or more characteristics

★ Must-know

• A universal concept applies without exception to all beings or situations in the same category, whereas a particular concept concerns one being or situation at a specific moment.

• An objective concept is independent of personal opinions and feelings and can be universal, whereas a subjective concept depends on an individual's perceptions or experiences.

• A belief is a personal and subjective conviction without absolute certainty, whereas knowledge is a true and justified belief that is objective and universal.

• An a priori truth can be known without experiencing the thing and is intelligible, whereas an a posteriori truth requires experience and is sensible.

Further detail

📌 An essential concept concerns a property necessary to an element's existence or definition, whereas an accidental concept concerns a property that is not necessary to what the element is.

📌 An abstract concept is based on ideas and is not physically accessible to the senses, whereas a concrete concept is tangible, perceptible, and observable.

💡 Memory Hook

Objective describes the shared fact; subjective describes personal experience.

📖 3. Ontology and Reality

🔑 Key Concepts & Definitions

• Ontology : a branch of philosophy that specifically studies being and existence

📝 Essential Points

📌 Realism holds that reality exists independently of the mind and senses and that objects exist even when they are not perceived, whereas idealism holds that reality is connected to the world of ideas and originates in the mind.

💡 Memory Hook

Realism locates reality outside the mind; idealism locates it in the world of ideas.

📖 4. Premises and Types of Reasoning

🔑 Key Concepts & Definitions

• Argumentation : the defense of a viewpoint on a debatable subject by formulating and arranging premises
• Premise : a starting proposition in reasoning from which a conclusion is drawn, and it provides the basic material of argumentation

★ Must-know

📌 A value premise declares something worthy or unworthy of esteem or prescribes an action as a moral duty, whereas a preference premise expresses a subjective taste that cannot rationally justify a conclusion.

📌 Deductive reasoning produces a conclusion that necessarily follows from its premises, while inductive reasoning uses repeated concrete observations to produce a conclusion that is probable but not guaranteed.

• An empirical premise can be verified through experimentation and is therefore a posteriori.

Further detail

📌 A reasoning consists of premises and a conclusion, with the premises serving as the starting points and the conclusion as the statement drawn from them.

• An analytical premise is necessarily true a priori, and definitions are essential examples of analytical premises.

💡 Memory Hook

Premises lead through reasoning to a conclusion.

📖 5. Obstacles to Rational Argumentation

🔑 Key Concepts & Definitions

• Relativism : the view that all opinions are equally valid because no objective truth exists
• Skepticism : Skepticism is the attitude that it is always possible to doubt the truth; doubt can begin philosophical inquiry but becomes dangerous when it suspends judgment indefinitely.
• Dogmatism : asserting claims without proof and refusing to examine potentially invalid premises

📝 Essential Points

📌 The antidote to relativism is to persist in rational effort and seek the best-argued opinions, the antidote to skepticism is to treat doubt as the first step toward knowledge without abandoning rational inquiry, and the antidote to dogmatism is to open oneself to dialogue.

💡 Memory Hook

Relativism abandons objective truth, skepticism doubts indefinitely, and dogmatism refuses doubt.

📖 6. Argument Quality and Fallacies

🔑 Key Concepts & Definitions

• Sophism : A sophism is reasoning that fails rational criteria and is used to deceive or persuade; sophisms originated in antiquity and remain present in modern discourse such as advertising.

★ Must-know

📌 Correspondence assesses whether a premise fits what the interlocutor has established and the role it plays in the reasoning, whereas coherence assesses a proposition through its relation to a set of other propositions when direct verification is impossible.

• 🔄 A good argument is assessed in three stages:
  1. The premises are acceptable.
  2. The premises are relevant to one another and to the conclusion.
  3. The premises are sufficient to establish the conclusion.

Further detail

• A false dilemma forces a choice between two opposed options even though other options exist, whereas an appeal to authority invokes a recognized person who is not an expert on the question.

• A hasty generalization applies a rule from particular cases to all cases, whereas a false cause infers that one event caused another merely because it occurred first.

• An argument from ignorance claims that a proposition is true because nobody can prove it false or false because nobody can prove it true.

• When complex empirical premises rely on experts, the expert should be recognized by other experts, work within the relevant field, be unbiased, belong to an expert consensus, and be represented accurately by the argument.

• The course identifies these sophisms:

  • False dilemma
  • Appeal to authority
  • Hasty generalization
  • Slippery slope
  • Intent fallacy
  • Appeal to novelty
  • False cause
  • Argument from ignorance

💡 Memory Hook

Acceptability, relevance, sufficiency: first assess premises, then their links, then their force.

📊 Synthesis Tables

Three Approaches to Truth

Approach	Method	Relation to truth
Philosophy	Logic, reflection, argumentation	Truth is examined, modified, and improved
Science	Observation and experimentation	Truth exists and is revisable
Religion	Belief, religious texts, family, tradition	Truth is fixed, with interpretation that may vary
