This question is about the video "The Twentieth-Century Poetic Revolution"
My ideas and opinions about the terms "modernism" and "modern art" have not changed after watching the video.
When researching the terms "modernism" and "modern art" before watching the video I realized that these terms are related to artistic movements that arose during a social change, or that caused a change in art and society, for this reason they are related with what is modern, new, different.
The video shows just that, as it presents the factors of change that influenced art and changed the whole society not only in its artistic perception, but scientific and religious as well.
