Below a certain level of education, the reading jumps over the image of  Einstein's  formula, and becomes  "Quablock is only Pigna. All the remaining is relative."  

An identity by semantic similarity followed by an opposition built on the term  "relative":  From which, one to all (post hoc ergo propter hoc) that reaffirms the first identity.  

 When  the formula of Einstein was recognized, it becomes the ironic visual premise of the second affirmation.  

For which: Identity by semantic similarity, opposition on the  general relativity, identity by similarity within  the opposition (All the rest is relative). From that the  only Quablock against all, an implication  that reaffirms the first identity (post hoc ergo propter hoc).
