"The World I Know" is a song by American rock band Collective Soul from their second studio album, Collective Soul (1995). Written by lead singer and guitarist Ed Roland, the song was released as the album's fourth single in October 1995. "The World I Know" peaked at number 19 on the US Billboard Hot 100 chart and spent four weeks at number one on the Billboard Album Rock Tracks chart. In Canada, the song reached number one on the week of March 11, 1996, becoming the band's highest-charting single there.

In a December 2017 interview with Songfacts, lead singer Ed Roland explained the inspiration behind "The World I Know":

I wrote that when we had a day off in New York City. This was 25 years ago, when we were in Times Square, which is not what Times Square is now, which is like Disneyland. There was still some grit and dirt to New York City - especially around Times Square and Union Square back then. I literally walked out of the room, took a two-hour walk around New York, and just absorbed and observed from the highs and lows of what society was offering in the greatest city in the world.^[1]

During an interview on The Professor of Rock YouTube channel with Adam Reader that was posted on October 10, 2022, Ed corrected Adam on the official authorship credits for this song. When Adam mentioned, "Co-written with Ross Childress...", Ed stopped him and stated, "No, not co-written. And, I'm going to say it right now, he didn't write a damn thing. He didn't even play on the song. He gets credit, 'cause he wanted credit. And, at the early time of a band, you want to make sure everybody's clear and cool. He didn't write a damn thing."^[2]

The music video depicts a businessman who begins to go about his day, reading The New York Times on the way to his office. As he reads about death, and sees the homelessness and sadness on the street, he becomes disillusioned with his life and prepares to commit suicide. As he climbs to the roof of a nearby building, he takes off his shoes and looks at the ground crying. He stretches out his arms and readies himself to fall. However, just as he is about to fall, a dove lands on his arm. He feeds it with the bagel in his pocket, and the crumbs attract ants, which makes the man notice the similarities of them to the people walking below. He laughs throwing all his money at the people and pulls himself out of his state.

During the entire video, periodic cuts to singer Ed Roland looking on at the man while singing the song are shown. The video also shows sadness and happiness in the form of color hues for the video. While the man is disillusioned with his life and is thinking about suicide, the video is in a blue and purple tint, giving a dark feeling to the video. When the dove lands on the man's arm, the video's hue changes to show the normal colors of the city, also revealing the sun shining over the city, showing of the sudden change to happiness and relief.
