# Level of Certainty

Discussion in 'Philosophy' started by GGrass, Mar 15, 2012.

1. Question even the most obvious.

Doubt even the most honest.

Suspect even the most innocent.

"Are you still so sure?"

2. Nope.

3. sounds like a poem almost. im only certain that this level is based on confidence with something or an experience.

4. To be certain is to lie to oneself.

5. Tell me something, that you have high level of certainty on.

What are you most certain about?

I am certain that the sun will rise from the east and set to the west.

6. A very good point.

Is it a lie to be certain?

7. By the definition of certain, yes it is.

Nobody can be certain 100% about anything.

There are things like you said for example, the sun rising from east to west, which are highly likely, and thus we can be fairly certain that it will happen.

That doesn't mean that when you wake up (if you do) tomorrow the sun will rise at all.

8. How about if I stated,

"The sun will rise from the east and set to the west for the next 1000 years."

Will that be a 100% certain statement?

Can anyone think of a reason why the sun won't rise from the east and set to the west?

May be the magnetic field of the earth might flip and east will become north and west will become south.

So may be after 755 years, the sun will rise from the north and set the the south.

Hm... possible?

Very unlikely, but nevertheless possible... so I guess you can't say with 100% certainty that the sun will rise from the east and set to the west for the next 1000 years... eventhough that sounded like a sure certainty.

9. A statement like that is more likely than the previous statement, but we still can't be without any doubt sure that you will be correct.

I personally am not a scientist, so I can't provide a reason as to why the sun might not rise in the east and set in the west in 1,000 years.

The only thing we can be certain of is our own ideas. Take mathematics for example. We know that two is two. We know that two plus two is always going to be four. There is 100% certainty there because it involves an idea.

The problem is our ideas can be wrong. It's hard to question two being two, because two is a concept?

Fucking damn it, sorry Ggrass, I'm too drunk for this!

10. No need to apologize. I'm loving it.

--

2 + 2 = 4

And it should be so no matter how many times you repeat that calculation.

You put two joints in your pocket, and you put another two, then there should be four joints in your pocket.

But why is that there's only three?

Because I smoked one joint earlier and totally forgot about it.

So I guess you can never be sure, that two plus two is always equal to four.

11. I ask anyone to please post something that you are most certain of.

And I'll make you doubt it.

12. Birthday.

My birthday, as shown on my ID card, is 7 Oct 1975.

But can I be sure that I was born on the 7th of October, year 1975?

May be I was born earlier, but my parents registered few days after. So may be my real birth date is 5th October, and not 7th of October.

May be when I was born, my mother died, and my father was freaking out, so nobody reported my birth, until three months later, my father finally got his sense back and registered my birth.

So may be I was born in July, and not October.

This kind of stuff could have happened to you, and you don't even know it because nobody told you.

--

You never know these things...

13. I can only be certain of the kind of things that can be expressed in recursive form.

For example, the statement, "a bachelor is an unmarried male", or "a triangle is an object with three sides", or "x is the case in all possible worlds, therefore x is a necessary proposition".

Any kind of sentences besides ones like that can't have that level of certainty.

Even if you said, "Barrack Obama is President", while that statement may be correspondent to a truth in the world, over time it will necessarily become false. Not as good as the kind of sentences I've typed above. There are alot of other ways that statements can be made to appear as though they express certainty, but without that recursive form, it's just rhetoric and persuasion.
