Possibly, "I do know that" can in fact only be used, when, you are answering the question of whether or not you know the issue at hand (or your knowledge has been called in to question, and you are answering that challenge). Let's say "out of the blue" you wanted to state that "you know that" -- and you wanted an emphatic version.
Why do you think that He doesn't know him from his schooldays means that he does know him? It would only have that sense if you added something like In fact, he first met him at university.
The sentence I'm writing goes like this: As much as I love the pure sciences, I know now a well-rounded education is valuable. But the words "know" and "now" are so similar that every time I read...

I don't know when we can use each of these phrases properly. Thanks and best regards,
It's not just you that doesn't know. Now, according to owl.purdue.edu, we should use "doesn't" when the subject is singular (except when the subject is "you" or "I"), and "don't" otherwise. But in the example above, I am having a hard time figuring out what exactly the subject is and whether it is singular.

You can also know someone and be getting to know someone at the same time – if you've learned a lot about that individual, but are also still learning new things about that person on a regular basis.
