What does 二系列の交叉点　mean?


I’m currently reading a Japanese text about political philosophy, but I can’t
put my head around the term **二系列の交叉点**. It comes up in the following sentence
and is frequently used afterwards.

人類と社会の未来と俺の未来、普遍への自己犠牲的献身と私的環境の中での現在のエゴイズム、この **二系列の交叉点** に立ってどちらかの択一を強制されている。

All possible translations I came up with didn't quite fit. Can anyone help me
out?




系列A：人類と社会の未来＝普遍への自己犠牲的献身。  
系列B：俺の未来＝私的環境の中での現在のエゴイズム。

二系列の交叉点とは系列Aと系列Bの交叉点。

Now you are standing at the center of the crossing of two ways: A and B. You
are forced to select one of the ways of living between A and B. To live for
the contribution to others or to live for your selfish way is the question.




系列A：人類と社会の未来＝普遍への自己犠牲的献身。  
系列B：俺の未来＝私的環境の中での現在のエゴイズム。

二系列の交叉点とは系列Aと系列Bの交叉点。

Now you are standing at the center of the crossing of two ways: A and B. You
are forced to select one of the ways of living between A and B. To live for
the contribution to others or to live for your selfish way is the question.
