EPTJust ask simple-worded questions to head these issues off. I don't know where your quote came from, but I do see the idea behind it. If you want to truly learn, then try to make the statement readable to the ordinary person - not necessarily understandable, but readable. I mean, "demystifying" can be simplified into "clarify", "praxis" into "practice" or even "experience" and so on (if I can follow the thought behind the quote). Precondition, if not really meant in its temporal sense, can be simplified into "condition" or "requirement" even. Thus you end up with "Clarifying the present is a requirement of practice (or if you want to keep the philosophical heritage of the term intact, praxis), which is necessarily future-oriented. (cut off the first thought there) This would be possible if the future were partially known." Two ideas then - (1) that some form of present clarity is required for praxis, and (2) that by the nature of praxis (in its future-oriented approach), partial knowledge of the future needs to be attained.
When you simplify things, it's not as complicated or "intellectual"-sounding as your quote made it out to be, and you can have a more fruitful discussion (with less "pomposity" thrown between thinking friends).
