Such help as we can give to each other in this world is a debt to each other; and the man who perceives a superiority or a capacity in a subordinate, and neither confesses nor assists it, is not merely the withholder of kindness, but the committer of injury.
John Ruskin (1872). “The Two Paths: Being Lectures on Art, and Its Application to Decoration and Manufacture, Delivered in 1858-9”, p.149
