How was ernest hemingway's writing a reflection of the ideals of the "lost generation"?

The phrase "Lost Generation" compiled by Gertrude Stein refers to former patriotic writers who emigrated from America and took part in other cultural patterns and environments of Paris and London. After the First World War, a group of young people were known under this term. The term originated when Gertrude Stein witnessed a conversation between the owner of a garage and a young employee, who was not aware of the rapid change of wheel on his car. Then the owner told him that he, like many others who grew up with war and tasted the bitterness of the war, lost the generation. Hemingway used it for his novel "The Sun Also Rises". He talks about the lack of motivation, purpose and instinct that arises from the great disappointment of the lost generation.

This was felt by all those who grew up in the war and were in their twenties and thirties. Many have lost faith in traditional values ​​such as courage, masculinity, patriotism. That is why they sought meaning in different cultural patterns. Some have become reckless, devoid of purpose, focused only on material values, without the ability to believe in any ideals.
