The formation of personality is accompanied by the formation of ideals that remain with a person for life. However, people are not always so strong as to remain faithful to what they believe. Usually they are condemned for this, but maybe you should not do this? Perhaps these ideals are already out of date, and do not cling to them?
Sometimes ideals really become obsolete, something new comes in their place, but a person does not have time to adapt to new realities. For example, in the play by A.P. Chekhov “Uncle Vanya”, the protagonist believed that his whole life has served science, and more specifically, its luminary, Professor Serebryakov. He and his niece worked free of charge, caring for the estate and managing the household, and all the money earned was sent to this scientist and his wife. So the heroes lived from year to year, not regretting their share. It seemed to them that they were pushing science forward with their contribution, that Serebryakov, without needing anything, would make discovery after discovery for the whole world. But they were wrong. The same professor arrived, but turned out to be only a complacent nonentity. He did nothing, only grabbed debts, because of which the estate needed to be sold. Ivan disappointed in his ideal, realizing that he had spent his whole life in vain on the maintenance of a dummy. Out of despair, he tries to shoot a relative and have an affair with his wife, but nothing helps him get rid of the thought that everything in the world is futile and perishable. As a result, he resigned himself to fate and continues to live in the old way. In his case, it was necessary to change beliefs for a long time, but he did not do this and lost everything.
In another example, the ideals of one person become the misfortune of all those around him. Marfa Kabanova, the heroine of the play “Thunderstorm” by A. Ostrovsky, tyrannizes household members, imposing Domostroy and his main tenets on them. The new generation disagrees with her, it is painful for them to live in lies and submission to what they no longer believe in. But Kabanikha does not want to change orders, she thinks that the same ideals hold the globe for many millennia. Ignorance prevents her from realizing the need for change. Therefore, her family, in the end, falls apart: Katerina ends her life by suicide, Tikhon rebels, Varvara runs away from home.
Thus, ideals can and should be changed if they do not correspond to common sense and the spirit of the times. A person should keep up with life, and not be fenced off from it by the errors and prejudices of the past, otherwise the world will cease to develop.
