Constructing Deductive And Inductive Arguments

Constructing Deductive And Inductive Argumentsarguments Consist Of Pre

Constructing Deductive and Inductive Arguments Arguments consist of premises and conclusions. Premises are structured so as to lend support to conclusions. The kind of support that a premise lends to a conclusion allows us to distinguish between deductive and inductive arguments. This week, you will be constructing both kinds of arguments.

1. In three premises each, construct one example of each following deductive argument form:· Modus ponens· Modus tollens· Hypothetical syllogism· Disjunctive syllogism Make sure your arguments are deductively valid and that your examples are your own. Here are two examples of the general format that your arguments should take: Modus ponens: 1. If it is raining, then it is pouring. 2. It is raining. 3. Therefore, it is pouring. Modus tollens: 1. If Jack went to the grocery store, then he bought cookies. 2. Jack did not buy cookies. 3. Therefore, Jack did not go to the grocery store. 2. After you construct the preceding deductive argument forms, construct a three premise syllogism. For example: 1. All men are mortal. 2. Socrates is a man. 3. Therefore, Socrates is mortal. 3. After you construct a three premise syllogism, construct one of each of the following inductive argument patterns:· Induction by enumeration· Reasoning by analogy· Statistical induction· Higher-level induction Your examples of inductive argument patterns should not be expressed in premise form. Rather, they should be informally expressed in writing. You should have one paragraph for each pattern. Be as detailed as possible. Finally, please remember to label your arguments. This makes it easier for them to be graded. Include your name, course section, and the date at the top of your assignment document. View your assignment rubric.

Deductive Arguments

Modus Ponens:

1. If the sunset is happening early today, then the sky will be orange at 6 PM.
2. The sunset is happening early today.
3. Therefore, the sky will be orange at 6 PM.

Modus Tollens:

1. If the algebra class is canceled, then the students will not attend.
2. The students attended the class today.
3. Therefore, the algebra class was not canceled.

Hypothetical Syllogism:

1. If it rains, the ground gets wet.
2. If the ground gets wet, then the soccer match will be postponed.
3. Therefore, if it rains, the soccer match will be postponed.

Disjunctive Syllogism:

1. Either the store is open or it is closed.
2. The store is not open.
3. Therefore, the store is closed.

Three-Premise Syllogism

All mammals have lungs. All dogs are mammals. Therefore, all dogs have lungs.

Inductive Argument Patterns

Induction by Enumeration

After observing many swans in the city park over several months, I have only seen white swans. From these numerous observations, I infer that all swans in the park are likely white. This pattern of reasoning, called induction by enumeration, involves observing specific instances and generalizing about the entire group based on those instances. It is a common form of reasoning in scientific investigations where repeated observation supports the formulation of general laws or conclusions.

Reasoning by Analogy

Consider two plants: one that has been growing in a well-lit window and another in a darker corner. The plant in the well-lit window has thrived, showing robust growth, while the one in the darker corner has shown stunted growth. By reasoning through analogy, I conclude that sufficient light is likely a key factor in plant health. When reasoning by analogy, similarities in observed cases lead us to infer similar behaviors or properties in new, analogous cases. This approach is useful in hypothesis formation and initial scientific assessments.

Statistical Induction

Research shows that about 70% of individuals who take a particular medication experience relief from symptoms. Based on this statistical data, I infer that a new patient with similar symptoms might also respond positively to the medication. Statistical induction relies on data from samples to make probabilistic assertions about populations or individuals. It underpins much of evidence-based medicine by translating research findings into individual treatments.

Higher-Level Induction

Many scientific theories are developed from previous theories and observed phenomena. For instance, the theory of gravity was developed after observing the falling of objects and existing Newtonian mechanics. Higher-level induction involves forming general scientific theories based on multiple instances and patterns observed across different fields or domains. This reasoning underpins the development of scientific laws and complex hypotheses, providing frameworks that organize empirical data into comprehensible models.

Conclusion

Constructing both deductive and inductive arguments requires careful attention to logical structure and evidence. Deductive reasoning aims at certainty, ensuring the conclusion follows necessarily from the premises, as seen in the argument forms like Modus Ponens and Hypothetical Syllogism. Inductive reasoning, meanwhile, relies on probability, making broad generalizations based on specific cases, patterns, or statistical data. Both forms of reasoning are crucial in scientific inquiry, philosophical debate, and everyday decision-making, highlighting the importance of understanding their principles and applications.
