Sentimentality
(重定向自Sentimentally)
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.
