"The system could not be breached; but it could at least be momentarily transgressed, probed for those neuralgic points where its authority faltered and unravelled. Fascinated by these fault-lines , one might even come to imagine that there is no centre to society after all;...but it could only be at the cost of acknowledging that there can logically be no margins either."
In the sentences above, we see some words that somehow relate to "physical place" but (I think) in metaphorical sense:
points, fault-lines, centre, margin
1.Given this relation, what does "fault-lines" mean here? 2.Do "breach" and "transgress" have also some connotations related to physical place? What do they mean here? Are they antonyms?
