In modern times "Sentimental" is a pejorative term that has been casually applied to works of art and literature that exceed the viewer or reader's sense of decorum—the extent of permissible emotion— and standards of taste: "excessiveness" is the criterion; for most of the twentieth century Tchaikovsky's symphonies were denigrated as "sentimental". "Meretricious" and "contrived" sham pathos are the hallmark of sentimentality, where the morality that underlies the work is both intrusive and pat.
Sentimentality applies feelings in inappropriate situations. The sentimental fallacy is an ancient rhetorical device that attributes human emotions to the forces of nature, such as mourning or anger.
Complications enter into the ordinary view of sentimentality when changes in fashion and setting— the "climate of thought"— intrude between the work and the reader. The view that sentimentality is relative is inherent in John Ciardi's "sympathetic contract", in which the reader agrees to join with the writer when approaching a poem. The example of the death of Little Nell in Charles Dickens' The Old Curiosity Shop (1840-41), "a scene that for many readers today might represent a defining instance of sentimentality", brought tears to the eye of many highly critical readers of the day.
