In opposition to Dewey's argument, it would be reasonable to contend that plasticity is inherent in all nervous substance.
"John Dewey's logical theory"
Delton Thomas Howard

"The Tempering"
Charles Neville Buck
As one turns the pages of Rilke's first small book of poems, published originally under the title Larenopfer, in the year 1895, and which appeared in more recent editions under the less descriptive name Erste Gedichte, one realizes at once, in spite of a lack of plasticity in the presentation, that here speaks one who has lingered long and lovingly over the dream of his boyhood.
