> Data does not equal Information

I would argue that the observation of anything which can be construed as "data" comes from more than just the raw data itself. The individual observing the data, for example, is comprised of many complex mechanisms which allow data to be observed. As such, it must be recognized that the individual is endowed with certain abilities allowing the observation, and that because such an endowment exists, it becomes an impossibility that any data existing around us is without information, but rather it is all a message given unto us, that if we inquire of it correctly, asking the right questions with regards to the observed data, we will find the information.

For example, we find an immense amount of "data" stored in DNA, and the more we learn about that data, the more we begin realize it so very clearly contains not only information, but a masterfully complex and purposeful conveyance of information at that.

> Information does not equal Knowledge

I would argue that information is, by definition, a repository of knowledge. It is a static subset of some larger set which exists, a road sign pointing the way to the thing. However, until we recognize it as such, we will not view it as knowledge, but only as "stuff" (some other nebulous quality that we cannot put a true name on, but only guess at when in reality the information is not there by accident, and it is up to us to inquire continually, seeking knowledge from the information we possess, that we may find the inherent truth).

> Knowledge does not equal Understanding

Given our faculties, that we possess the innate ability to attain knowledge and acquire understanding, I would argue that as long as one is in pursuance of the truth, then a continual gain of knowledge does equate to understanding (because the one who put the data there, which was of information, and the information there, which was of knowledge, also put the knowledge there, which is of understanding).

In short:
Seek the truth and you will find all things. Ignore the truth and you can invent whatever you want to explain what otherwise continually and perpetually existed and exists as Knowledge and Understanding, for these things are absolutes which exist without regards to man's ignorance.

Man is the lacking component of the equation in gaining understanding. It is not the thing which is incomplete, but only man's desire to pursue the thing rightly which is incomplete (and even then only when man is not truly seeking, for when man seeks rightly, the truth is found).
