Here are highlights from Stage 2 of the Tour Down Under.

Propositional form X is contingent (i.e., X is a contingent propositional form) iff (1) it is possible for X to be true and (2) it is possible for X to be false. In other words, X is neither necessarily false nor necessarily true.

Example from everyday life: 'x is taller than y'

Example from categorical logic: 'Some S are P'

Example from propositional logic: '(p ﬤ q) ﬤ p'

Example from predicate logic: '(x)Øx'

Here is Ann Coulter's latest column.

Anderson Bruford Wakeman Howe (1989).

Despite a glowing medical report for President Trump, journalists are saying that he's obese &c. The question is not whether he is perfectly healthy, or even how far removed he is from perfect health; it's whether he's healthier than the alternative, which was Hillary Clinton. The answer is obviously yes. She is far more obese than Trump is, and, oh yes, she passes out from time to time. How much alcohol does she drink, anyway? What does she eat? How, if at all, does she exercise? How many hours per night does she sleep? Do you suppose any of these questions would have been asked if she had been elected? It would have been sexist and insulting. Those who asked the questions would have been vilified. Journalism today is nothing more (or less) than propaganda in the service of progressivism.

Regarding “Reason as Racism: An Immigration Debate Gets Derailed” (Jan. 15): This is the most disappointing of editorials I have read from your board—not because of a political difference but because of your lack of moral clarity.

Calling Donald Trump a racist is not name calling; it’s merely stating the obvious. Consider his renting tactics from the 1970s, defending white supremacists in Charlottesville, lack of commitment to Puerto Rico, calling Mexicans rapists, and Muslim bans. It is one thing for people at work or people at the corner bar to speak this way. It is quite another for our president and supposedly the moral center of the entire world to do so. His words are a reflection on all of us.

And if you think we should stop calling each other names, consider: crooked Hillary, lying Ted, Pocahontas, low-energy Jeb, etc. Your position needs some self-reflecting.
