The general idea of this sentence is that there are too many things in life that seem as light as a feather, but in fact they are unbearable.
Kundera reveals the unbearable lightness of human life, but he, like us, is unable to solve this problem. Because it is impossible to "never return". National history and personal life are only one-off. Without the preliminary arrangement and draft, the choice becomes meaningless. We don't choose kitsch, what else can we choose? Isn't Anzhi's determination and courage to fight against kitsch another kind of kitsch? How can a person living on the earth avoid kitsch? If kitsch is inevitable, aren't all "difficult resolutions" as light as a feather?
This is another unbearable lightness in life. Kundera thus expressed doubts about the ultimate meaning of life, which our predecessors took for granted and firmly believed. We have no choice but to choose. We have always opposed kitsch and kitsch.
There are many "unbearable burdens" in a person's life, such as work, life, feelings, interpersonal relationships and so on, which vary from person to person. But people often ignore that there is "unbearable lightness" in life! There may be many reasons why a person living in a stress-free world has no pressure, such as he is pampered and well-fed; For example, he is not enterprising, doing nothing all day, like a walking corpse; For example, he escapes from reality, sees through the world of mortals and escapes into an empty door ... these are all negative ways of doing things. This "stress-free" life will not make people feel "heavy" but "relaxed", but this kind of "relaxed" will ruin a person, drown him in the world of mortals and accomplish nothing. Therefore, this kind of "lightness" is unacceptable, and it should not be borne in life, and it cannot be borne!
