Can any statement be turned into a conditional statement?

Postby MS415 » Sat Dec 08, 2012 1:58 am

Can any of the following statements be turned into conditional statements?
1. Fred is the only one wearing a red shirt.
Could this be " If he is the only one wearing red shirt, then he is Fred" or
" If he is Fred, he is the only one wearing a red shirt"?

2. Katie is driving to school in a pink Beetle.
Could this be " If she is driving a pink beetle, then she is Katie" or " If you are Katie, then you are driving a pink Beetle"?

Your answers would be very much appreciated. Thank you in advance.

The only introduces sufficient ,so if Fred is the only one then he is wearing a red shirt
but the second one o don`t think so.

First statement: If wearing a red shirt, then it's Fred.

"The only" introduces the sufficient condition.

Second statement: not a conditional.

"The only" introduces the necessary condition.

Second statement: not a conditional.


Fixed.

"the only one" is a necessary condition, and refers to Fred here.

Nope. "The only" always introduces the sufficient. The "THE" preceding "only" is the trigger.

You're right on introducing the sufficient, but that won't result in the bolded.

As others have said, "the only" introduces a sufficient condition. In this case, it introduces, "one wearing a red shirt."
So if you diagrammed this, it would be:
Wearing a red shirt -> Fred

However, this is also an absolute statement that tells me Fred is, in fact, wearing a red shirt. While it's not great, you can change an absolute statement into a conditional (see below), though it usually sounds stupid:
If you are the Fred in question, you're wearing a red shirt.

So the statement you wrote above is actually bi-conditional, because I know Fred is wearing a red shirt, and no one else is wearing a red shirt. So if you find me someone who is wearing a red shirt, then I'll be sure it's Fred; and if you blindfold me and have Fred say hi, I'll astound him by telling him his shirt is red. And if you introduce me to anyone else, I know their shirt isn't red. Ditto find me someone in a blue shirt - I'm sure it's not Fred.

2. Katie is driving to school in a pink Beetle.
Could this be " If she is driving a pink beetle, then she is Katie" or " If you are Katie, then you are driving a pink Beetle"?


Again, this is an absolute statement. If you were going to force it into a conditional statement, it would be:
If you are the Katie in question, then you are driving to school in a pink Beetle.

However, I would just leave this one as an absolute statement (I usually represent that with a colon instead of an arrow, so K:DTSIB, which means Katie is driving to school in a Beetle).

as in:

i will play if tony will play
tony play --> i play

i will play only if tony will play.
i play --> tony play


Yes, that is right but when you have the following preceding only, for example, the following:

IF only
THE only


these introduce the sufficient.

Example: The only way to be a licensed attorney is to pass the bar (License --> Pass bar)

BP talks more about this, as well as "unless", "without", "except", etc.:
