Chapters 1-2 Flashcards
What is logic?
Logic is the study of the principles and methods of good reasoning. It is a science of reasoning which aims to determine and lay down the criteria of good (correct) reasoning and bad (incorrect) reasoning.
Why is logic important?
We can clarify our ideas, assess the acceptability of the claims and beliefs we encounter, defend and justify our assertions and statements, and make rational and sound decisions.
Psychology v. Logic
Psychology deals more with HOW people reason. Logic studies the principles of good reasoning.
How is logic applied in the field of law?
In interpreting the constitution and statutes, when we balance fundamental principles and policies and when we evaluate evidence and make judgments to render legal decisions.
What is an argument?
It is a claim put forward and defended with reasons. It is a group of statements in which one statement is claimed to be true on the basis of another statement/s.
Conclusion v. premise
Conclusion - statement being claimed to be true
Premise - statement that serves as the basis or support of the conclusion
Explanation v. Argument
Explanation - attempt to show why something is the case
Argument - attempt to show that something is the case
*explanations are not meant to prove or justify the truth of a particular claim.
What is an issue?
Any matter of controversy or uncertainty; an issue is a point in dispute, in doubt, in question, or simply up for discussion or consideration.
Relevance of the premises depend on this.
According to Richard Neumann, what are the three parts of a rule?
1) A set of elements, collectively called a test
2) A result that occurs when all the elements are present (and the test is thus satisfied)
3) a causal term that determines whether the result is mandatory, prohibitory, discretionary, or declaratory
Stare decisis principle
Legal doctrine that obligates Courts to follow past decisions on similar cases
What is a non sequitur?
A conclusion or reply that doesn’t follow logically from the previous statement.
What are the components of legal reasoning?
- Issue
- Ruling
- Facts
- Analysis (How applicable are the facts to the said rule?)
- Conclusion (What is the implication of applying the rule to the given facts?) - ultimate end of a legal argument
What are some of the things to consider in the analysis?
a. intent b. overt acts c. pattern of conduct d. emotional distress
Argumentum ad ignoratio elenchi or ignoration elenchi
Irrelevant conclusion
- missing the point
- fails to address the issue at hand
Criteria for evaluating correct/incorrect legal reasoning?
Truth and logic
1. presentation of facts which pertains to the question of truth and 2. inference (deriving a legal claim or judgment from the given laws and facts) which pertains to the question of logic
1 - Are the premises provided in the argument true or acceptable? - legal reasoning shall be grounded on truth and genuine facts
2 - Is the reasoning of the argument correct or logical? Does the conclusion of the argument logically follow from its premises?
Burden of proof
It is the duty of any party to present evidence to establish his claim or or defense by the amount of evidence required by law, which is preponderance of evidence in civil case.
Burden of proof always lies on those who asserts something because he who denies a fact cannot produce any proof of it.
Burden of proof is the duty of the party alleging to prove his claim.
Equipoise doctrine
When the evidence of the parties are evenly balanced or there is doubt on which side the evidence preponderates, the decision should be against the party with the burden of proof.
Evidence
Evidence is the means sanctioned by the Rules of Court, of ascertaining in a judicial proceeding the truth respecting a matter of fact.
Can be a document or by testimony of witness
Best evidence rule
Rule 130, Section 3 of Rules of Court
applies only when the CONTENT of such document is the subject of inquiry. Where the issue is only as to whether such document was actually executed, or exists, or on the circumstances relevant to or surrounding its execution, the best evidence rule does not apply and testimonial evidence is admissible.
Admissibility and Relevance
Admissible if relevant to the issue and not excluded by provision of law or by the Rules of Court
Relevance - must have such a relation to the fact in issue as to induce belief in its existence or non-existence (credible dapat)
Testimony of Witnesses
Witness must have personal knowledge
Expert Testimony
Statements made by individuals who are considered experts in a particular field.
Methods of Examination
Direct examination by the proponent
- exam by the party presenting him on the facts relevant to the issue
Cross-examination by opponent
- by the adverse party to test accuracy, truthfulness, and freedom from bias
Re-direct examination by the proponent
- to explain or supplement established facts
Re-cross-examination by the opponent
After this had been concluded, the witness cannot be recalled unless there is leave of court
Dependence on Precedents
Stare decisis et non quieta movere. “to stand by and adhere to decisions and not disturb what is settled”
What’s more important in legal reasoning? Legal basis or facts?
Legal basis. It is the premise.
Generally how many premises do we have?
2 distinct premises because it would be vague to mash 2 ideas into one.
