ZOMG!: A Social Media Novel - Kane X. Faucher

He could not help but to ponder the potentially lateral meanings of Ezra Pound´s statement, "Technique is the touchstone of an artist´s sincerity."

lateral adj 1) of, at, towards, or from the side or sides; the plant takes up water through its lateral roots.

-[ANATOMY] & [ZOOLOGY] situated on one side or other of the body or of an organ, especially in the region furthest from the median plane. The opposite of medial.

Not that I disagree with Pound´s statement, or Faucher´s inclusion in the text, but I had to look up lateral in the (online) dictionary, and I still don´t understand the meaning of it here in context *confused look*
