2 ways of moving from a premise

You have a premise you can reason out what is necessary for the premise to be true ( either the premise is a direct consequence or shares ascendant cause with these ideas), and you can reason out what is a consequence of the premise. While these two types are in most respects the same, I find that it is useful to address the time domain; where the first would be hints already in place and the later being things that follow after. This distinction is one of personal preference for addressing causal determinants.
