Analogues
Items being compared.
Have primary and secondary analogues
Analogical reasoning
Reasoning that depends on a comparison of instances. If instances are sufficiently similar, the decision reached in the end is usually a good one. But if they are not sufficiently similar, the decision may not be good.
Principles useful for evaluating most arguments from analogy
- Relevance 2. Number of similarities 3. The nature and degree of diasanalogy 4. Number of primary analogues 5. Diversity among the primary analogues 6. Specificity of the conclusion
Aalogical arguments in law
Based on precedents
Differences of analogical arguments used inlaw
- Smilarity is more elusive and is up to creativity of lawyers to find similarities in cases
- Not all primary analogues (ex. Previous cases) hold up same weight

Te methods of agreement, difference, and concomitant variation resemble the methods used by scientists to identify casual connections
Method of agreement
Identifies necessary conditions
Method of difference
Identifies sufficient conditions
Join method of agreement and difference
Identifies sufficient and necessary conditions
Method of residues
Ientifies generic casual connections
Mthod of concomitant variation
Ientifies generic casual connections
Hypothetical reasoning
Used to solve a problem when solution is not readily apparent
Four basic stages of hypothetical reasoning
Occurance of a problem
Formulating a hypthesis
Drawing implications from the hypothesis
Testing the implications
Four examples of hypothetical reasoning from science
Radium by marie curie
Neptune by adams and leverrier
Atmospheric pressure by torricelli
Refutation of spontaneous generation by louis pasteur

Empirical
Theoretical
Empirical hypothesis
Can be proved true or false
Theoretical hypothesisq
Can be confirmed in various degrees
