Keats' attitude is upbeat and enthusiastic. Tone and mood are connected to the overall feeling of a work. Everything in the Ode to Autumn is basic, plain, and unambiguous. The poem is characterized with a calm tranquillity throughout. There are no dramatic scenes, only a reflection on how nature has changed since springtime when everything was in bloom. The last two stanzas express an optimistic view of humanity's future: "And man shall be as free As birds in air Or fish in water - / Free to ascend or descend According as the spirit moves him." This conclusion brings us back to where we started: life is full of change, but it also shows that despite our differences we can all co-exist peacefully. There is no one right way to think or feel, only different ways which all seem valid to some degree. This idea is one that many poets have expressed through poetry. It can also be seen in paintings and sculptures which represent mankind as being equal parts good and evil. Artists such as Keats were interested in questions about reality and morality, so their work often deals with these topics in some way. Autumn is one of Keats' most famous poems and it has been interpreted by many artists over the years. In addition to painting, it is also well-known as a text piece due to its use in schools across the world.
