Difference Between Knowledge and Understanding

"I know that it's snowing"

"I understand that it's snowing"

Are they the same or different and why or why not?

I understand what you're asking, and I don't know the answer. I hope this helps.

Thanks but I'm still confused precisely because I know what you're saying but I don't understand it

So you're saying knowledge has to do with certainty, whereas with understanding you could not be certain but yet still understand.

And you're saying understanding has to do with understanding the concept whereas knowledge has to do with answers or truth

Why can't one know the concept (since obviously one can understand the truth - or no)

So would you say in understanding, the account of how you understand it is somehow unconscious whereas in knowing you can give a conscious account of how or why you know?

What do you meant by tone?

5 stars.

It seems that knowledge alone never has meaning and the understanding 'adds' this meaning to the knowledge. 

But then how could one understand something without knowing it - is it just that you are not certain of the proposition that you understand (and so you don't know it)?

Indeed. It is quite simple. You cannot have understanding without knowledge. Although you can acquire knowledge without understanding (trivia for example) that's the difference.

Knowing swindles, opening traps, Legal's legacy, triangulation are great. Applicable in certain situations or positions immediately upon recognition. Understanding why they work takes time.

You both agree that you can't have understanding without having knowledge but what if you're not certain about a fact? You could understand that fact, then, without knowing it

I think that knowledge means you know the particular bit or item of knowledge, whereas understanding means you understand the relation between one item (whether you know that item or not), and another item

In other words, knowledge is of particulars whereas understanding makes a claim about something general (ie what the two items generally have in common)

You could know (and so perceive in your mind) the answer but unless you conceptualize what is it that you're seeing and tie or synthesize it into the greater system that you are dealing with, you won't have understanding. And consequently you can understand something that you don't know because you're not confident on betting your life on the supposed knowlegde for example

This point goes back to the idea that you may know something but not know how to implement it in practice precisely because you don't understand it (how it relates to the system that is the world)

Or to be more precise, how it coheres with the system (with the system of beliefs that make up your world as you perceive it empirically)

That's why understanding in dreams is very limited (if at all really), because a dream is all a priori perception (perception by projection in your mind) and not the world that you see while awake

You know what's happening in your dream but you don't understand why

Whereas in waking life you know what's happening and you understand it

Because the empirical world is governed by laws of nature that enables the understanding to function by introducing concepts to it. Knowledge is nothing more than common concepts. And understanding is applying these concepts in judgments in practice
