Kanye West hopes his unborn son ''can feel purpose.''

The 38-year-old rapper, whose wife Kim Kardashian West is set to give birth in December, admits they still haven't agreed on a name for their baby boy, but is excited to see what he will accomplish in the future.

Asked what he and the reality TV star, 34, are planning to call the tot and his hopes for him as he gets older, he said: ''I don't have a name for him, but what I hope for him is that he can feel purpose.''

The 'New Slaves' hitmaker, who also has two-year-old daughter North with the brunette beauty, thinks it's important that their children experience feelings of desperation and failure.

He explained to Anna Wintour during a one-on-one with the SHOWStudio team at Paris Fashion Week: ''The other night I was driving in Paris, and I saw these three high school kids running top speed. I didn't know if they were chasing a guy or what, and there was a bus on the side of the street that was about to pull off, and they were beating on the side of the bus. And I looked at the time and it was like, 1 a.m., so that might be the last bus of the night, and I was just like, really saddened.

''I was like, 'How can I make my son feel that?' Because once you've felt that, then none of these f**king questions matter. When you've missed that last bus before, when you have the opportunity to get on the bus? You don't give a f**k about any of this. And having to sleep downtown in a parking lot, it's almost like not feeling anything. It's almost like being numb because of what I went through.''
