Reading as Construction (1980)
“See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.”

“Reality, at first glance, is a simple thing: the television speaking to you now is real.”
                                        
                                        What Is Reality? 
Context: Reality, at first glance, is a simple thing: the television speaking to you now is real.

They can be measured with a yardstick, a voltammeter, a weighing scale. These things are real.

Context: Man is constantly being assured that he has more power than ever before in history, but his daily experience is one of powerlessness. … If he is with a business organization, the odds are great that he has sacrificed every other kind of independence in return for that dubious one known as financial.
