Gerald E. Wright JR PHIL 1250 16 Jun 2016 What does the world "philosophy" mean (in terms of ancient Greek roots)? Philosophy - From the Ancient Greek word ?????????, philosophia) It translates literally to "love of wisdom? It is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language What does the word "logic" come mean (in terms of ancient Greek roots)? Logic - From the Ancient Greek word ??????, logike Originally meaning the word, or what is spoken, but coming to mean thought or reason Is generally held to consist of the systematic study of the form of arguments. Define validity: An argument is valid if and only if it is impossible that its premises are all true and its conclusion false. What is the difference between a valid argument that is sound and one that is unsound? (Think about this one before answering) Sound - A deductive argument is sound if and only if it is both valid, and all of its premises are actually true. Unsound - A deductive argument is unsound if it is valid, and any of its premises are not true. Is the following argument valid or invalid? All As are Bs. Some Bs are Cs. So some As are Cs. If invalid, explain a case in which the premises could be true and the conclusion false. Invalid, there is the possibility that no As are Cs due the fact that Cs could fall outside the sphere of influence of the As Is the following argument valid or invalid? No As are Bs. All Bs are
2) Deductive logic starts with a premise and applies it to a specific case to reach a conclusion
For the purposes of this essay it is important to establish what is meant by a valid and a sound in relation to arguments. The Internet Encyclopedia of Philosophy defines valid and sound in respects of philosophical argument. A argument is
An argument is an attempt to prove that something is true (or probably true) by offering evidence. In philosophy there are usually three premises that are part of the argument. Premises are evidence used to attempt to prove the conclusion. The third premise is the one that sums up that argument. Arguments can be objectively true or subjectively true. For an argument, x is objectively true if and only if x is the case, and x is subjectively true for S if and only if x coheres with S’s worldview of X is simply a matter of taste.
In assessing the argument, it can be said that it is a valid argument since the conclusions logically follow from the arguments given they are true.
This is a deductive argument. A deductive argument is an argument that is intended by the arguer to be deductively valid. As the deductive arguer here I am attempting to provide the truth of the conclusion that is provided by my arguments premises and they should be true statements.
With your second argument is more of a deductive argument as premise one and two are true and the conclusion is guaranteed. So this would be a valid deductive argument. For an inductive argument the conclusion should
To analyze this argument we must first have an understanding of the argument for validity. An argument is logically valid if and only if there is no consistent story in which the premises are true and the conclusion is false. If an argument is not valid it is then invalid. To be aware whether an argument or pair of sentences are valid, we make use of the validity test. To prove this consistency, we must follow these effortless elements- (a) List premises with negation of conclusion, (b) Show that no consistent story “hits target” from (a), (c) Apply definition of validity, and (d) Apply definition of soundness. For example, let’s assess these next couple of statements that
An argument is a disagreement between two or more individuals based on ones beliefs or opinions with the purpose of disproving the other person’s beliefs or opinion. There are four elements to make an argument legitimate, and then you have to present the evidence for that argument. Then there is the counterargument where you have to defend your claims followed by your rebuttal where you will have to show all of the evidence you have to disprove the other person argument that they have against yours. If you can present these elements it will show your level of research and intelligence about the subject that is in question.
This argument has convincing premises; however, it lacks legitimate evidentiary support leading it to be an invalid argument.
My argument I found it to be valid, and for my premises to be true. It is also true that for an argument to be sound the conclusion must also be true, which also makes my argument a good one.
An argument is valid whenever the conclusion must be true if the premises are true.
Arguments are defeasible, they are not incorrigible, thus defeaters can be presented; therefore, the cumulative case approach of combining a number of arguments to make the case is the best
Throughout chapter four in Everything’s an Argument, we learn about arguments based on reason and evidence. While both terms may seem similar and are used to strengthen an argument, they both do different things. Evidence, as opposed to reason, refers to anything factual and pre-existing, such as facts, statistics, laws, contracts, witnesses, documents, or any other form of data. Evidence is classified by inartistic proofs, which is the arguments the writer or speaker is given. On the other hand, reason refers to artistic proofs which is an argument the writer creates. If someone does not have the facts to support their claims, they will use reason and common sense. Reason is used to strengthen an argument and may appeal to emotions and logic,
This is not a logical argument because belief does not instantly imply truth. The premise of an argument is
c. Errors in logic, or fallacies, can make an argument appear weak and unconvincing. Read about good arguments versus fallacies, and complete the five exercises. Then write two syllogisms of your own that are based on fallacies, and explain their logical errors. You might choose from these fallacies: validity problem, post hoc, slippery slope, straw man, inconsistency, begging the question, false dilemma, non sequitur, and ad hominem.
