Emotions can be revealed through arts. A sad song can show how unhappy someone is, using lyrics and melody. In contrast, science can show the causes and effects of sadness and depression in a person. For instance, a psychologist can write a report explaining the reasons why someone feels depressed, while the depth of the sadness cannot be shown in such scientific reports.
Art depicts the beauty in everything. A painting of a marvellous landscape at sunset, using different colours can display the beauty in nature. This cannot be done by science, because it only speaks about the wavelength of the sun rays.
Human values can be depicted through literature. A novel about the story of a boy coming from a poor background who tries hard and waits many years to become successful can show the value of patience. Scientific books can only use logic to convey the message that patience is important.
People can develop their imagination and creativity through art. Art enables people to use their imagination to create things that do not exist. For instance, someone can paint a flying car that does not exist.
In conclusion, different types of art can help people show their feelings, depict the beauty of something, the value of abstract ideas, such as patience, and let their imagination go wild.
