Quick question to any logicians. Is this argument valid? I dont care about soundness, only if this argument is valid:
The sun always rises in the east.
Tomorow is a part of always.
The sun will rise in the east tomorow.
Or is this argument circular?
Well, I would say that “tomorrow is part of always†is ok, but that does not mean that the sun will rise in the east, as the sun is not part of “always†because the sun is a finite object.
The sun could blow up tomorrow, the Earth could get knocked off of it’s orbit, or get destroyed.
Also, does the sun rise in the east on all sides of the planet?
Oh boy, I was not asking about the soundness of the argument. I dont actually think its sound. I want to know if it is not valid, thats all. I need people that know the distinction between valid and sound! Where can I find these people!
A valid argument follows from its premises and a sound one is true.
Thanks… So is mine valid?
Only humans can reason.
Bob can reason.
Thus, Bob is a human.
That’s sound.
Only Fish have scales.
A gecko has scales.
Thus, geckos are fish.
That’s valid, but not sound.
GOD DAMNIT ALDERIAN, ANSWER THE DAMN QUESTION~!!! IS MY ARGUMENT VALID OR NOT!!!
There is something funny about the “tomorrow” part in the second line. Perhaps something should be mentioned about it in the first line.
Thinking…
Like…
The sun will always rise tomorrow in the east.
Tomorrow is part of always.
Thus, the sun will rise tomorrow in the east.
Still something sounds funny.
That doesn’t even seem to be an argument.
Here’s a valid version of your “argument” in SD
C: Therefore the sun will rise in the east
E 1,2–>E
If you’re wanting to use predicate logic which is probably the case then you’re out of luck as I don’t have the necessary characters on my key board to make a translation into logic. The best I can do is put it in easily translatable terms.
Therefore tomorrow is such that the sun will rise in the east
If the sun always rises tomorrow in the east
and tomorrow is part of always
Then, the sun will rise tomorrow in the east.
maybe this?
I turned it into an “if then” kind of thing.
The sun will always rise tomorrow in the east
Tomorrow is part of part of always
Thus, the sun will rise in the east.
I made the first sentence a premise.
Maybe the weird part is the word tomorrow as there is no such time as “tomorrow†because it is figurative. There’s something weird.
This thread makes me want to read Hemingway.
This implies more that WHEN the sun rises, it rises in the east.
Otherwise it would have to be taken as ‘the sun is always rising’, which from any one perspective it isn’t.
So this can not mean the sun will always rise, only that it can only come from the east, soo…
Doesn’t imply the sun will rise during time period ‘always’, only that it can only rise from the east during time period ‘always’
There is no indication that ‘tommorow’, being a very small fragment of ‘always’, will contain the event 'rising sun
No, this isn’t a valid argument.
Yep, it’s the always thing!
Okay, thanks Satanical, I see your point. What about nihilistics translation:
Therefore tomorrow is such that the sun will rise in the east
Is this valid?
Or better yet, what about this one:
The sun is such, that every day, it rises in the east
Tomorow is a day
Therefore, the sun is such, that tomorow, it will rise in the east
and even better, how about:
1.If the sun rises, it rises in the east.
2.The sun rises once every day
3.Tomorow is a day
4.Therefore, the sun will rise once in the east tomorow.
This last one is the one I like most. So how about it? Is it valid?
I bet it’s valid anyway, because I also bet that tomorrow has something to do with morrow, has something to do with morning, has something to do with sunrise.

So…
“The sun will rise in the east tomorrow” because tomorrow means the next time the sun rises. But only if the sun always rises in the east. But the sun doesn’t always necessarily rise in the east… what if the polarities get fucked up? Back to dictionary.com we go.
At first, it appears that it doesn’t work:

n.
adj.
adv.
In, from, or toward the east: a river flowing east.
BUT THEN:
[b]east
(1.) The orient (mizrah); the rising of the sun. Thus “the east country” is the
country lying to the east of Syria, the Elymais (Zech. 8:7). (2). Properly what
is in front of one, or a country that is before or in front of another; the
rendering of the word kedem. In pointing out the quarters, a Hebrew always
looked with his face toward the east. The word kedem is used when the four
quarters of the world are described (Gen. 13:14; 28:14); and mizrah when the
east only is distinguished from the west (Josh. 11:3; Ps. 50:1; 103:12, etc.).
In Gen. 25:6 “eastward” is literally “unto the land of kedem;” i.e., the lands
lying east of Palestine, namely, Arabia, Mesopotamia, etc.

The bible is very old. Older than knowledge of the polarities. Yes, I know it’s not English, but it was directly translated to that at least. And the word east may be older than knowledge of the polarities. So… “the sun will rise in the east tomorrow” may be perfectly valid and sound.
MUAHAHAHAHAHHAA! I <3 linguistics.
Just for kicks:

Anyway, if anyone wants to investigate the age of the word east and the first recorded knowledge or record of discovery of the knowledge of the polarities, let me know.
Etyology of the word east, from etymonline.com:
east Look up east at Dictionary.com
O.E. east, from P.Gmc. *aus-to-, *austra- “east, toward the sunrise” (cf. Du. oost, Ger. Ost, O.N. austr “from the east”), from PIE *aus- “dawn” (cf. Skt. ushas “dawn,” Gk. aurion “morning,” O.Ir. usah, Lith. auszra “dawn,” L. aurora “dawn,” auster “south”), lit. “to shine.” The east is the direction in which dawn breaks. For shift in sense in L., see Australia. Meaning “the eastern part of the world” (from Europe) is from c.1300. Cold War use of East for “communist states” first recorded 1951. Natives of eastern Germany and the Baltics were known as easterlings 16c.-18c. The east wind in Biblical Palestine was scorching and destructive (cf. Ezek. xvii.10); in New England it is bleak, wet, unhealthful. East End of London so called from 1846; East Side of Manhattan so called from 1882; Eastern Shore of Maryland and Virginia so called from 1624. East Indies (India and Southeast Asia) so called 1598 to distinguish them from the West Indies.
IT WORKS!!
The argument goes:
Therefore, Tomorrow is a time the Sun will rise in the East.
The argument is not valid, since it does not follow necessarily from the fact that the Sun has always risen in the East, that it will rise in the East tomorrow.
However, I would bet on it if I were you.
The argument certainly isn’t circular. If it were circular it would be valid.
Dammit read my post! I WORKED FOR THAT POST!!
