The correct answer is: "If we remembered everything, we should on most occasions be as ill off as if we remembered nothing". This fact can be seen in the case of Russian journalist S, who forgot very little but, because of this ability, had difficulty with <em>abstract</em> thinking.
Abstract thinking is defined as the capacity of to think about ideas, facts, objects, thoughts, and principles that are not physical. Theses ideas are abstract because they escape the concept of "here and now" and take thinking to a deeper more symbolic level.
