Recognizing Argumentsin This Assignment You Will Apply Key Concepts C

Identify the component parts of the argument, premises and conclusion, for the following passages. Where applicable, highlight key words or phrases that identify a claim as a premise or a conclusion. Refer to the following example: “All men are mortal. Socrates is a man. Therefore, Socrates is mortal.” All men are mortal.

Premise: Socrates is a man.

Premise: We know already this child has no genetic anomalies. If Sue’s baby is a boy, he will be named Mark. If Sue’s baby is a girl, she will be named Margaret. Sue will have either a boy or a girl. So we know Sue’s baby will be named Mark or Margaret.

Premise: This is because all fantasy novels are fiction and all works of fiction are housed on the second floor of the library.

Premise: Brain scans showed that among the walkers, the hippocampus had increased in volume by about 2 percent on average; in the others, it had declined by about 1.4 percent. Since such a decline is normal in older adults, a 2 percent increase is fairly significant,’ said the lead author, Kirk Erickson, a psychologist at the University of Pittsburgh. Both groups also improved on a test of spatial memory, but the walkers improved more. While it is hard to generalize from this study to other populations, the researchers were delighted to learn that the hippocampus might expand with exercise.

Identify Arguments as Inductive or Deductive

Offer a brief explanation why each argument is either inductive or deductive. (Remember that in this exercise you are not concerned with whether the arguments are strong or weak, valid or invalid. You are only concerned with the form of the arguments—that is, whether they are deductive or inductive.)

1. Because Una has circles under her eyes, is yawning, and looks tired, I’m certain she didn't get much sleep last night.
2. Grace concluded that psychotherapists caused indigestion, because every time she had a session, she left with a horrible stomachache.
3. If a bug is a spider, it must have eight legs. A daddy-longlegs has six legs, consequently, a daddy-longlegs is not a spider.

Argument Identification and Analysis

In the following longer text passages, identify the key components of each argument. For each argument, list the main conclusion and the reasons (or premises) that support the conclusion.

Issue 1

“You say many women at the most elite colleges intend to ‘put aside their careers in favor of raising children.’ But why shouldn't the raising of children be considered a career as well? Few would deny that being a stay-at-home parent is a terrifically demanding job, requiring unlimited 'people skills' and a total commitment to a workweek that recognizes no concept of overtime, not to mention a paycheck. The term 'working mother' is a redundancy. No woman need feel any guilt for opting to fill her days with whichever activities give her the greatest joy and fulfillment.” (English, 2005)

The author concludes that: Raising children should be considered a valid career, and women should not feel guilty about choosing activities that bring them joy and fulfillment.

The reasons for making the argument are: Being a stay-at-home parent is a demanding job that requires specific skills and commitment; the term 'working mother' is redundant; women have the right to pursue activities they find fulfilling without guilt.

Issue 2

“The attorney general does not merely head up the Justice Department. He is responsible for ensuring that America is a nation in which justice prevails. Mr. Gonzales's record makes him unqualified to take on this role or to represent the American justice system to the rest of the world. The Senate should reject his nomination.” (The New York Times, Editorial, 2005)

The author concludes that: The Senate should reject Mr. Gonzales's nomination as attorney general.

The reasons for making the argument are: He is unqualified to ensure justice prevails in America; his record raises concerns about his ability to represent the justice system effectively.

Constructing Original Arguments

Inductive Argument

Conclusion: Increasing physical activity improves hippocampal volume and spatial memory in adults.

Supporting reasons: Studies show a 2 percent increase in hippocampal volume in walkers versus a 1.4 percent decline in non-walkers; both groups improve on spatial memory tests, but walkers improve more; exercise has potential to reverse age-related hippocampal decline.

This is an inductive argument because it draws a general conclusion based on specific empirical observations. The premises are based on observed data from a particular study, and the conclusion extrapolates that regular exercise can benefit hippocampal health generally. As with all inductive reasoning, the conclusion increases in probability but is not guaranteed, reflecting the nature of empirical evidence and scientific generalization.

Deductive Argument

All mammals with six legs are not spiders.

Daddy-longlegs has six legs.

Therefore, daddy-longlegs is not a spider.

This is a deductive argument because it applies a general rule to a specific case, leading to a logically certain conclusion. The premises guarantee the conclusion if true, which is characteristic of deductive reasoning. The structure follows a logically valid syllogism with a clear logical progression from general to specific.

Finding an Argument from Media

Example: A recent news article states, “Vaccines are effective in preventing COVID-19, as they have significantly reduced infection rates in populations with high vaccination coverage.” (Source: Example News Outlet, 2022)

The argument is deductive in form because: It relies on empirical evidence that high vaccination rates correlate with reduced COVID-19 infections, implying that vaccines cause the reduction. The conclusion that vaccines are effective is supported by the premise that higher vaccination coverage results in fewer infections. The reasoning follows the pattern that if certain conditions (vaccination) lead to specific outcomes (lower infection rates), then the efficacy of vaccines is established.

This reasoning is deductive because the evidence seeks to establish a guaranteed link—if vaccination coverage is high, infection rates decline, indicating vaccine effectiveness.
