Phi 103 Informal Logic for Further Information Review The Documentpres

Review the document "Presenting Arguments in Standard Form". Choose a topic of interest for your final paper that you feel capable of creating strong arguments on both sides. Find one source presenting a view on one side of your chosen topic, which does not need to be scholarly but could be a newspaper or internet article. Present the main argument made by this source in standard form, with premises listed above the conclusion. Without taking sides, evaluate whether this source provides a strong representation of reasoning on that side of the issue. Consider the clarity of the argument, ways to strengthen the reasoning, and how to objectively understand the issue. A minimum of 50 words is required.

Topic: Is the Earth flat?

In support of the idea that the Earth is flat, rapper B.o.B (2016) tweeted, “The cities in the background are approx. 16 miles apart... where is the curve? please explain this,” alongside a picture of himself on a mountain top with a cityscape in the distant background. His argument, expressed in standard form, is:

• P1. If the earth wasn’t flat, then the curvature of the earth would be visible in the distance.
• P2. There is no curvature visible to partially block the cityscape approximately 16 miles away.
• C. Therefore, the earth is flat.

B.o.B's statement clearly presents his reasoning, particularly through premise 2, which is based on his observation of the cityscape from 16 miles away. He expects the curvature of the Earth to be visible at this distance if the Earth is spherical. However, his argument would be stronger with an explicit connection between the non-visibility of the curve and the conclusion that the Earth is flat. Additionally, he should clarify whether the curvature of Earth should be visible at 16 miles, taking into account the Earth's size and the limitations of human vision.

Evaluating the argument, premise 2 appears believable, as the absence of visible curvature at that distance lends some support to his conclusion. Nevertheless, the first premise requires more detail: scientific knowledge about Earth's curvature and visibility limits is essential. Without such data, the argument's strength depends heavily on empirical observations and scientific principles.

To objectively analyze this issue, one should consider scientific measurements and calculations of Earth's curvature, as well as optical limitations. For instance, the Earth's radius (~3,959 miles) suggests that the curvature at 16 miles should be visible under ideal conditions. The apparent discrepancy may be due to atmospheric refraction or other factors affecting visibility.

Furthermore, scientific experiments and geographical data support the spherical nature of Earth, making the flat Earth argument less convincing without additional empirical evidence. By understanding the science behind Earth's shape and the reasons for the non-visible curvature, individuals can form more rational opinions about the issue.
