Suppose you take a photo of a mountain from a mile away. Do you have to view the image from a mile away to have correct perspective?

Although I did not copy the whole chapter, a little later on he says:

"For correct perspective, therefore, a contact print should be viewed at a distance equal to the focal length of the lens. An enlargement should be viewed at a distance equal to the focal length multiplied by the degree of enlargement."

No need to go a mile away!!!

By the way, a contact print is a print made at the same size as the image on film (or on the sensor if you translate it to the digital age). Of course, nobody makes prints that small these days.

This diagram (from the Manual of Photography) may help:
