Late Homework Option

In the spirit of the season, I decided that I would offer a short period of "homework forgiveness."

Here's how it will work.

Three slots will be opened on Turnitin. In these slots you may submit any 5 point written assignment, thus, anything except for the recent blog/paper on homosexuality - that you might have not completed or you did not do as well on it, grade-wise, as you would like. You must also turn these assignments in, in hardcopy, by Monday, April 1, in class.

No late work will be accepted: absolutely none. And, any work not turned in hardcopy in proper format, with email, class time, and Turnitin receipt will not be considered.

This work will be graded on the basis of quality and quantity, its being complete and detailed, among other considerations.

Insights from the Fred Feldman page abortion:

1.     Precision: - all (actual)? Some? Which? All possible?
2.     Meaning.. what do you mean?
3.     Logically valid arguments

An action is “prima facie” wrong = wrong unless extreme circumstances justify it
      Contrast w/ “absolutely” or “necessarily” wrong..

Suppose someone says that they believe that, “Abortion is prima facie wrong.”
 If you asked them, “Why do you think that?” what reasons would they give?

Updates, new assignments, quiz, etc.

1. Your paper or blog/webpage on arguments about homosexuality is now due next Monday, March 25, instead of this Friday. This was extended on Monday. And, please upload your project to Turnitin: if you do a blog, do your best to cut and paste the relevant sections into a document to upload.

2. Monday we discussed an article on gun control - 

The N.R.A.’s Blockade on Science - 

by philosopher Gary Gutting from the NY Times. We will look at some of the other articles in this series soon, especially 

Why Gun ‘Control’ Is Not Enough

Mid Course Survey!

Survey!

Paper /project assignment 1, with some of options. All due Friday, March 22.



Paper /project assignment 1, with some of options. All due Friday, March 22.

First, re-read Vaughn on writing  philosophy and this article by James Pryor, "Guidelines on writing a philosophy paper": http://www.jimpryor.net/teaching/guidelines/writing.html 

Option 1: Individual philosophical paper or educational webpage/blog where you address all the aspects of the assignment below.

Option 2: Group project:
The purpose for this assignment is for you to construct a public online teaching tool to help people better find and evaluate moral arguments and then apply this guidance to the issue of homosexuality. (Your teaching tool can, and probably will, be used with other issues later in the semester ). Create your own group of 2 or 3 students. Create a webpage or blog (on Blogger, Wordpress, Google Sites, wherever) where you present and evaluate at least five arguments for the conclusion that homosexuality is wrong.

You must also explain the methods that you will use to evaluate these arguments, in terms of finding conclusions, finding premises, making the arguments valid and identifying whether the arguments are sound or not (including using counterexamples to try to argument that general moral premises are false). That is, you must explain *how* someone would think about moral issues and explain the methods that we’ve used in this class.

On your page(s), you must:

- Identify what you mean by the claim that 'homosexuality is wrong'; this might be different for different arguments.
- Identify at least five arguments for that conclusion: pick arguments that you think are interesting, common and/or influential.
- State these arguments in logically valid form.
For each argument, explain whether each premise is true or false and so whether the argument is sound or not.

Your webpage/blog should have an introduction and a conclusion and so forth.

The purpose for this assignment, instead of a paper, is for you to construct a public teaching tool to help people better find and evaluate moral arguments and then apply it to the issue of homosexuality. (Your teaching tool can, and probably will, be used with other issues later in the semester!).

Please email Dr. Nobis the URL, post a link to your page on the blog (below this post) and bring a printout of the page to class! Make it very, very clear who is part of your group.

Some notes on syllogisms

Please read this:

Richard Feldman on “Simple Moral Arguments”: http://sites.google.com/site/nobisphilosophy/feldman-simple-moral-arguments.pdf


BELOW WE COMPARED MAKING THESE ARGUMENTS LOGICALLY VALID BY WAY OF ADDING A GENERAL PREMISE, TO FORM A SYLLOGISM, VERSUS ADDING A PREMISE TO MAKE A MODUS PONENS ARGUMENT. 


Please make these arguments logically valid:

1.     Socrates is a man. If Socrates is a man, then Socrates is mortal.
2.     All men are mortal. = Any man is mortal. = If someone is a man, then that someone is mortal. = If X is a man, then X is mortal [ALL, ANY , IF-THEN]
3.     Therefore Socrates is mortal.

4.     Suzy is a Spelman student. If Suzy is Spelman student, then Suzy plays PP.
5.      All Spelmanites play PP. If Suzy goes to Spelman, then she plays PP. Anyone who is a Sp.. plays PP.
6.     Therefore, Suzy plays ping pong.

7.     Running is a sport. IF running is a sport, then running is dangerous.
8.     All sports are dangerous. Any … If activity X is a sport , then X is dangerous.
9.     Therefore, running is dangerous.

10.  Onions are fruits.All fruits are healthy. Anything that’s a fruit is healthy. If something is a fruit, then it’s healthy (If a food is fruit, then it’s healthy)
11.  Therefore, onions are healthy.


------------------------------



1.     Homosexual sex is not reproductive.
2.     All sex that is not reproductive is wrong. = If a sexual behavior is not reproductive then it’s wrong. = Any sexual behavior that’s not reproductive is wrong . F
3.     Therefore, it’s wrong.

Homosexual sex isn’t reproductive. T
All (any) sexual behavior that is not reproductive is wrong =
If a sexual act is not reproductive, then it’s wrong. F
Therefore, homosexual sex is wrong.

1.      
2.     Socrates is a man.      If Socrates is a man, then he’s mortal.
3.     All men are mortal. =
If X is a man, then X  is mortal.
            Therefore, Socrates is mortal

4.     Suzy is a Spelman student. If Suzy is a Spelman student, then she plays PP.
5.     All Spelman students play ping pong.
Therefore, Suzy plays ping pong.

6.     Running is a sport [?]. If X is a sport, then X is dangerous. F If running is a sport, then it’s dangerous.
Therefore, running is dangerous.

7.     Onions are fruits (f). All / any  / if -> then (all?) (some?) Fruit is healthy ??
8.     If onions are fruits, then they are healthy to eat­­.
Therefore, onions are healthy to eat.
