a cow has four legs so everything with four legs is a cow true of false?

Answer 1

The argument that you put as an example is fallacious. That means that there is a fallacy (error) in the argument. Put properly, the example argument would go like this:

A cow has four legs
All animals have four legs
Therefore all animals are cows.

The error is in the distribution of the terms. Cows ===> Legs is in one premise. Animals ===> Legs is in the next premise. Legs and Cows should be on opposite sides of the premises.

All animals have four legs
Cows are animals
Therefore cows have four legs.

Any analysis like this assumes that all of the premises are true. For example, insects have six legs and arachnids have eight. So it is not strictly true that "All animals have four legs." This is called an Aristotelian definition. The most famous is "All of the animals that live in the sea are fish."

A refutation of the above argument would be, "Major premise denied." That means that the person is not allowed to assert in the first place that all animals have four legs.

Answer 2

A chicken has two legs so everything with two legs is a chicken, man included, true or false?

Jokes apart I think it' s very true because a chair is a cow and a cow is a chair. It' s as simple as that.

By the way now that you remind me: today I'm going to milk the table I then shall put a glass of mik on it and sit on the cow to drink it. Philosophy is such a fun game!

Answer 3

Now, cows are not raised to moan or complain about little things. You steal their milk and sell it in your supermarkets. And now you talk about their legs that you might find amusing so that you may have your good share of laughter, which you might already have had by now, and therefore now it is logic time. According to inductive logic it can be induced through limited observation that the way of the cow is in fact the way every living thing walks, but a wider observation proves this to be untrue, that not all things in the world choose to stand on their all four as firmly as cows do. But then what else cows do? They moooo, when they see humans bi-pedling along their way, never fully stable and comfortably balanced.

Answer 4

It depends on who is driving. Well, if I am driving the answer is yes because one time I was driving to a hike with some friends and saw some cows out of the corner of my eyes and said, "Look! Cows!" The people in the car with me corrected me and said that they were not cows but horses. By then we had passed the cows so I had no way of verifying that the people in my car were correct and since I was driving I say that they were cows.

For the record, the cows did have four legs and they were grazing in a field.

Answer 5

Everything with 4 legs can be different animals. The dna inside tells us if it is a cow, or something else.

Answer 6

False

Answer 7

No... it just means that the cow fits into the four-legged category, not the other way around

Answer 8

False. My dog has four legs and trust me he isn't a cow, nor is my cat.

Answer 9

False let me demonstrate.

"All wood burns," states John Smith. "Therefore," he concludes, "all that burns is wood."

This is, of course, pure bullshit! Universal affirmatives can only be partially converted. All of Alma Cogan is dead, but only some of the class of dead people are Alma Cogan. Obvious one would think.

However, my wife does not understand this necessary limitation of the conversion of a proposition. Consequently, she does not understand me. For how can a woman expect to appreciate a professor of logic if the simplest cloth-eared syllogism causes her to flounder.

For example: given the premise, "All fish live underwater" and "All mackerel are fish", my wife will conclude, not that "All mackerel live underwater", but that "If she buys kippers it will not rain" or that "Trout live in trees" or even that "I do not love her any more."

This she calls "using her intuition". I call it "crap" and it gets me very IRRITATED because it is not logical!

"There will be no supper tonight," she will sometimes cry upon my return home.

"Why not?" I will ask.

"Because I have been screwing the milkman all day," she will say, quite oblivious of the howling error she has made.

"But," I will wearily point out, "even given that the activities of screwing the milkman and getting supper are mutually exclusive, now that the screwing is over, surely then, supper may, logically, be got."

"You don't love me any more!" she will now often postulate. "If you did, you would give me one now and again so that I would not have to rely on that rancid Pakistani for my orgasms!"

"I will give you one after you have got me my supper!" I now usually scream, "but not before" -- as you understand, making her bang contingent on the arrival of my supper.

"God, you turn me on when you're angry, you ancient brute!" she now mysteriously deduces, forcing her sweetly throbbing tongue down my throat.

"**** supper!" I now invariably conclude, throwing logic somewhat joyously to the four winds, and so we thrash about on our milk-stained floor, transported by animal passion, until we sink back, exhausted, onto the cartons of yoghurt....

I'm afraid I seem to have strayed somewhat from my original brief. But in a nutshell, sex is more fun than logic. One cannot prove this, but it IS in the same sense that Mount Everest IS, or that Alma Cogan ISN'T.

Goodnight.

Answer 10

If that's true I'm sitting on a cow right now!
