a question concerning the context
The passage below is from ‘the Blank Slate’ by Steven Pinker.
http://evolbiol.ru/blankslate/blankslate.htmSaying that the brain solves these problems because of its “plasticity” is not much better than saying it solves them by magic. Still, in this chapter I will examine the latest scientific objections to human nature carefully. Each of the discoveries is important on its own terms, even if it does not support the extravagant conclusions that have been drawn. And once the last supports for the Blank Slate have been evaluated, I can properly sum up the scientific case for the alternative. In this passage the three underlined parts seems to represent the same thing in different statements.
Am I right?
