Name 5 Sources of Knowlege:
1.) Reference to Tradition

2.) Reference to Authority

3.) Trial and Error

4.) Logical Reasoning

5.) Scientific Method
Accepting certain truths as given describes which source of knowlege?
Reference to Tradition
What are the probelms to Reference to Tradition as a source of knowlege
1.) Not evaluated for validity (closes the door for any opportunity to compare to alternative)

2.) Not tested against potentially superior alternatives
Placing trust in those who are experts on an issue is an example of which Sources of Knowlege?
Reference to Authority
  • Reference to Authority may be useful if..
Scientific evidence is weak or unavailable
Applying multiple attempts to find a solution by chance is an example of which sources of knowlege?
Trail and Error
When do you use "trial and error" as a source of knowlege?
When no other option exists
What are the problems of having Trial and Error as a source of knowlege?
1.) Haphazard and unsystematic process to obtain knowlege that is .... not shared, limited in scope, time consuming

2.) Prevents identifying/confirming the best solution
What are the problems of having Trial and Error as a source of knowlege?
1.) Haphazard and unsystematic process to obtain knowlege that is .... not shared, limited in scope, time consuming

2.) Prevents identifying/confirming the best solution
Name 2 types of logical reasoning?
1.) Deductive reasoning "top-down"

2.) Inductive reasoning "bottom-up"
Systematic method for drawing conclusions by linking premises and conclusions
(Logical Reasoning)

Deductive reasoning "top-down"
Developing generalization from specific observations
Logical Reasoning

Inductive Reasoning "bottom up"


Problems with Inductive reasoning:
1.) Quality of the knowlege derived from the inductive reasonin gis dependent upon how well specific observations represent the general situtuation

2.) Can't be absolutely certain of hte conclusion, b/c/ one must observe ALL possible examples of the events

3.) Conclusion is probable baed on observations
Sources of knowlege that involves applying a logical sequentail process to develop a conclusion
Scientific method
- Identifying the problem or question

- Organizaing a collection of data

- Objectively analyzing the data

- Interpreting the finds
