What is a person likely to do if his eyes sparkle with scorn for everything and everyone crossing his path?
About the Precocious Autobiography....
Yevgeny Yevtushenko, A Precocious Autobiography (1963).
First, let's define "scorn" and its synonyms. Scorn is identified by Random House Dictionary (on Dictionary.com) as functioning as a noun and a verb. When functioning as a noun (a feeling), scorn means open contempt and disdain. The example is "His face...showed the scorn he felt." As a verb (a behavior) scorn means to treat someone or something with contempt or disdain and also to reject, refuse or ignore someone or something with contempt or disdain. The example of this latter one is "She scorned my help." A third meaning as a verb is to act in such a way as to mock or jeer.
Both the noun and verb forms of scorn are derived from Germanic words that entered Old French, then entering Middle English between 1150 CE and 1200 CE. The noun derives from the Old French word escarn taken from one of the Germanic words like skern meaning "mockery." The verb form of scorn entered Middle English from the Old French word escharnir, which is also derived from one of the Germanic words like skern. The Germanic word itself derives from the Latin word scornare meaning "treat with contempt."
Let's go a little deeper into the meaning and look at the synonyms that keep coming up, contempt, disdain and mock. The word "contempt" means having the feeling that someone or something is the object of complete disrespect; worthless or vile; despised. The word "disdain" also means to despise and treat as being completely unworthy. The word "mock" means to attack or treat someone or something with ridicule; to challenge or defy someone or something.
Now to your question. Someone whose eyes sparkle--or flare--with scorn for anyone and anything that crosses his path is likely to speak contemptuously, be antagonistic, be insulting, pick quarrels, always speak in a offensive manner, feel superior and arrogant, not make friends, not smile, sneer, frown, get into fights if the recipient of the insults is on the aggressive side.
Does this quote reference describe Yevgeny Yevtushenko or another individual in the autobiography? If it describes Yevtushenko, the above list is well suited because his biographers say he spent his young years in street fights with the other boys and that he had a way of speaking unpopular truths in school that got him into trouble.
