You have perhaps concluded that people are not objects to be valued for their qualities or riches rather than for themselves. But elsewhere Yeats asks the question: How can we separate the dancer from the dance? Is it possible to separate ‘the person himself or herself’ from how the person looks, sounds, walks, and so on? Think of how you or a friend or member of your family has changed over the years. Has your relationship also changed? In what way?

It is true that people are not objects. They are living beings with feelings. They have power to think and act. They have wisdom to do what they want. They have life since objects are deprived of such qualities. We should value a man for his self only keeping in view his qualities as well.
The poet wants to express here that we cannot separate a man from his characteristics. He explain this with an example that a dancer cannot be separated from dance. But it is possible since time and circumstances have their own role to play in this world. His relations with other living beings, looks, sounds, walks and the other factors also work. Circumstances and luck can make or mar the destiny of a person. Here are many cases where we can see them in a great change. Within years they become so prosperous that none can believe. But a real person maintain his relationship in the most appropriate and desirable way. He never expresses his pride in any case.
