The author's specist position projecting humans as the only animals able to utilize memory signals a common humanist ontological position. The dichotomous statement separating humans from the rest of the animal kingdom is reinforced when a few sentences later he suggest that human intelligence (which we can already tell is being praised as the superior intelligence) is "the root, the fountain of human intelligence."

The issue is we have a plethora of research into the cognitive cognition in other species, for instance corvids, not to mention our own anecdotes, i.e. having the memory of an elephant.
