Logic / Reasoning Flashcards
What is Logic?
The studying of argumentation
What are the two parts of an argument?
The premises and conclusion
What is a valid argument?
One which the conclusion adequately follows from the conglomeration of premises
What is a valid argument?
One which the conclusion adequately follows from the conglomeration of premises
Is the truth of the conclusions or premises correlated with the soundness or validity of the logical structure of an argument?
No. One can maintain a conglomeration of premises that are mendaciously erroneous in their nature, however, still designate and materialize a sound conclusion, independent of the deprivation of “truth” that’s characteristic of the premises.
Does the truthfulness of the totality of premises necessitate a logically sound conclusion?
No. You can have a collection and aggregation of premises that are all factually veracious however the structure of the logical argument can be invalid, resulting in the arrival of an erroneous conclusion.
What is Deductive Reasoning?
an argument in which the truth of the premises necessarily guarantees and necessitates the veracity and verisimilitude of the conclusion.
What is Deductive Reasoning?
an argument in which the truth of the premises necessarily guarantees and necessitates the veracity and verisimilitude of the conclusion.
What is Inductive Reasoning?
A structure of an argument where the truth of the premises gives good reason to believe the conclusion, but does not absolutely guarantee the truth of the conclusion.
What are the limitations of inductive reasoning?
You can never institute a conclusion from the modality of inductive reasoning without additional background information and knowledge concerning the subject. In other words, you cannot engage in the extraction and extrapolation of a conclusion from a conglomeration of data and research without additional information concerning the subject.
Who was Karl Popper?
A philosopher of science whom engaged in the delineation of his dubiety towards scientist being motivated to inaugurate processes of inductive reasoning. Scientists only effectuate deductive reasoning to guide their conclusions, and for all other data, actuate a methedological machination of falsification.
Falscificationism:
Falsificationism, as opposed to verificationism, claims that the main activity of a researcher is to invalidate a theory by observation or experiment. The confirmation or corroboration of a theory can only rely on the failure of attempted falsifications.
What are some exemplars of deductive reasoning?
p. All students in this class take notes p. John is a student of the class C. therefore, John takes notes.
What is an example of inductive reasoning?
The teacher wrote on the chalkboard everyday, therefore, the teacher will write on the chalkboard tomorrow.
Is-Ought fallacy?
deduce a conclusion about what ought to be, on the basis of what is.
What is the Natural Fallacy?
any attempt to define the word good in terms of some natural quality; example : Breastfeeding is the natural way to feed children. Therefore, mothers ought to breastfeed their children and ought not to use baby formula
Non-sequitor fallacy
When the conclusion doesn’t logically follow from the premises
Continuum fallacy
The fallacy is the argument that two states or conditions cannot be considered distinct (or do not exist at all) because between them there exists a continuum of states.
False dichotomy;
two alternative statements are given as the only possible options when, in reality, there are more
Slippery slope
asserting that a proposed, relatively small, first action will inevitably lead to a chain of related events resulting in a significant and negative event and, therefore, should not be permitted.
Begging the question
using the conclusion of the argument in support of itself in a premise (e.g.: saying that smoking cigarettes is deadly because cigarettes can kill you; something that kills is deadly
Hasty generalization
basing a broad conclusion on a small or unrepresentative sample
Genetic fallacy
The genetic fallacy (also known as the fallacy of origins or fallacy of virtue) is a fallacy of irrelevance that is based solely on someone’s or something’s history, origin, or source rather than its current meaning or context.
Appeal to the stone
Dismissing a claim as absurd without demonstrating its’ absurdity
