Sentimentality originally indicated the reliance on feelings as a guide to truth, but current usage defines it as an appeal to shallow, uncomplicated emotions at the expense of reason.

Sentimentalism in philosophy is a view in meta-ethics according to which morality is somehow grounded in moral sentiments or emotions. Sentimentalism in literature is both a device used to induce a tender emotional response disproportionate to the situation at hand, (and thus to substitute heightened and generally uncritical feeling for normal ethical and intellectual judgments), and a heightened reader response willing to invest previously prepared emotions to respond disproportionately to a literary situation.

"A sentimentalist", Oscar Wilde wrote, "is one who desires to have the luxury of an emotion without paying for it."James Baldwin considered that 'Sentimentality, the ostentatious parading of excessive and spurious emotion, is the mark of dishonesty, the inability to feel...the mask of cruelty'.

In the mid-eighteenth century, a querulous lady had complained to Richardson: "What, in your opinion, is the meaning of the word sentimental, so much in vogue among the polite...Everything clever and agreeable is comprehended in that word...such a one is a sentimental man; we were a sentimental party". What she was observing was the way the term was becoming a European obsession - part of the Enlightenment drive to foster the individual's capacity to recognise virtue at a visceral level. Everywhere in the sentimental novel or the sentimental comedy, 'lively and effusive emotion is celebrated as evidence of a good heart'. Moral philosophers saw sentimentality as a cure for social isolation; and Adam Smith indeed considered that "the poets and romance writers, who best paint...domestic affections, Racine and Voltaire; Richardson, Maurivaux and Riccoboni; are, in such cases, much better instructors than Zeno" and the Stoics.
