Paper for above instructions
In evaluating the given arguments, it is essential to analyze their foundational structure, assessing their clarity and identifying any hidden premises that may not be explicitly stated. Additionally, we will determine whether each argument is sound, meaning that the premises support the conclusion and that the premises are true. This analysis will guide us towards a rephrased and robust argumentation.Argument Analysis
1. Having great wealth is a worthy goal because it is difficult to attain and many famous people have pursued it.
Revised: Having great wealth is a worthy goal because it is difficult to attain, as evidenced by many famous individuals who have pursued it to enhance their status or impact.
Evaluation: While the difficulty of attaining wealth is a valid point, the mere pursuit of wealth by famous people does not inherently confer worthiness, suggesting a hidden premise that wealth is intrinsically valuable. This argument is unsound.
2. Low grades on a college transcript are a handicap in the job market, so teachers who grade harshly are doing students a disservice.
Revised: Low grades on a college transcript can negatively impact students' job prospects; thus, teachers who grade harshly may hinder their students' future success.
Evaluation: This argument is clear and structurally sound, provided the premise about job market competitiveness holds. This argument can be deemed sound, as it is based on observable outcomes.
3. The Bible can’t be relevant to today’s problems; it was written many centuries ago and is filled with archaic phrasing.
Revised: The Bible is irrelevant to contemporary problems because it was written in a different historical context and uses archaic language that may not apply to modern life.
Evaluation: The argument fails due to the assumption that ancient texts cannot offer valuable insights relevant to current issues. Hence, it is unsound.
4. It is dishonest to pretend to have knowledge one does not have, so plagiarism is more virtue than vice.
Revised: Plagiarism is a complex issue; while it is dishonest to claim false knowledge, suggesting it as a virtue overlooks the ethical implications of causing harm to original creators.
Evaluation: The reasoning is faulty; equating plagiarism with a virtue conflicts with societal ethics. This argument is unsound.
5. The credit card habit promotes careless spending, particularly among young people. Therefore, credit card companies should not be permitted to issue credit cards to anyone under age 21.
Revised: Careless spending is prevalent among young people due to credit card habits; thus, preventing credit card issuance to those under 21 could mitigate this issue.
Evaluation: This argument highlights a valid concern. However, it lacks empirical evidence suggesting a direct causation of restricting credit would ensure responsible spending, making it unsound.
6. No one who ever attended this college achieved distinction after graduation. Marvin attends this college. Therefore, Marvin will not achieve distinction after graduation.
Revised: Statistical evidence suggests that attendees of this college do not commonly achieve post-graduation distinction; therefore, by attending this college, Marvin is unlikely to achieve distinction.
Evaluation: This argument can be sound depending on the truth of the premises and the logical structure; however, it's prudent to examine potential outliers.
7. Drug dealing should not be a crime because it does not directly harm others or force them to harm themselves.
Revised: While some argue that drug dealing does not directly cause harm, it neglects the broader societal impacts and consequences of substance abuse, revealing the complexity of the issue.
Evaluation: The argument presents a one-dimensional view of a multifaceted issue and is therefore unsound.
8. A mature person is self-directing, so parents who make all their children’s decisions for them are doing their offspring a disservice.
Revised: Self-direction defines maturity; thus, parents who make all decisions for their children inhibit their emotional and psychological growth.
Evaluation: This is a sound argument, as it relies on developmental psychology principles regarding independence and maturity.
9. There’s no point in attending Professor Drone’s class; all he does is lecture in a boring monotone.
Revised: Professor Drone's lectures lack engagement due to his monotone delivery, suggesting that attending his class may not enhance learning experiences.
Evaluation: While subjective, the argument is sound because it reflects the direct impact of teaching methods on learning efficacy.
10. Power must be evil because it can corrupt people.
Revised: Although power can lead to corrupt behavior in individuals, the simplistic notion that power itself is inherently evil lacks nuance and overlooks its potential for positive outcomes.
Evaluation: This argument is oversimplified and therefore unsound.
11. If the theory of evolution is true, as scientific evidence overwhelmingly suggests, a human being is nothing more than an ape.
Revised: If evolution is valid, humans share a common ancestor with apes; however, equating humans simply as "nothing more than apes" diminishes the complexity of human evolution.
Evaluation: The argument overstates the interpretation of evolutionary theory, making it unsound.
12. Rock musicians are contributing to the decline of language by singing in a slurred, mumbling manner.
Revised: While certain rock musicians may use unclear diction, attributing a decline in language solely to them ignores broader societal factors influencing language evolution.
Evaluation: This argument lacks a robust foundation, leading to the conclusion that it is unsound.
13. If emphasis on error paralyzes effort, this college is paying my English professor to make it impossible for me to learn English.
Revised: A focus on errors can hamper learning; however, education systems must balance opportunity for correction with motivation, and blame should not fall solely on individual instructors.
Evaluation: This notion is overly simplistic; thus, the argument is unsound.
14. Nuclear power is a threat to world peace. Nuclear energy stations generate nuclear power. So nuclear energy stations are a threat to world peace.
Revised: Nuclear energy stations can pose risks regarding weapons proliferation and environmental disasters; therefore, their role in global peace remains contested.
Evaluation: The premise aligns with global discourse on nuclear issues, making it relatively sound, but requires more specificity.
15. Lew Fairman is the best candidate for governor because he is in favor of the death penalty.
Revised: Lew Fairman supports the death penalty, which aligns with some voter values, but determining the 'best' candidate requires more substantial policy evaluation.
Evaluation: This argument is weak, as it focuses on a single issue without context, leading to unsound conclusions.
