Arnold's "want of logic and thoroughness of thought" as noted by John M. Robertson in "Modern Humanists" was an aspect of the inconsistency of which Arnold was accused. Few of his ideas were his own, and he failed to reconcile the conflicting influences which moved him so strongly. "There are four people, in especial," he once wrote to Cardinal Newman, "from whom I am conscious of having learnt – a very different thing from merely receiving a strong impression – learnt habits, methods, ruling ideas, which are constantly with me; and the four are – Goethe, Wordsworth, Sainte-Beuve, and yourself." Dr. Arnold must be added; the son's fundamental likeness to the father was early pointed out by Swinburne, and was later attested by Matthew Arnold's grandson, Mr. Arnold Whitridge. Others such as Stefan Collini suggest that much of the criticism aimed at Arnold is based on "a convenient parody of what he is supposed to have stood for" rather than the genuine article.
