“For whatever deserves to exist deserves also to be known, for knowledge is the image of existence, and things mean and splendid exist alike.”

deserve is a bit overdone here but other than that, hmmm, ok

Yes things are good to be known.

Indeed.

It is human nature to learn what is not known and to look for patterns to explain why things are the way they are. People learn like fish swim. Anyone who would deny knowledge to a man denies him his natural existence.

I should like to think this is a bit obvious...

The cloak of truth has no color, and yet each of us ware a different color - I am therefore I must exist - this knowledge is essential if we are to evolve.

"...for knowledge is the image of existence..."; i.e, our perceptions define our selves and the world in which we place those selves.
