"A people without the knowledge of their past history, origin and culture is like a tree without roots"

This quote by Marcus Garvey suggests that without an understanding and gratitude of one's cultural heritage and history, a group of individuals will lack a sense of identity and instructions. The referral to a tree without roots symbolizes that without a strong connection to their history and origins, a people can not grow and prosper. Basically, Garvey is highlighting the significance of understanding and valuing one's cultural identity in order to accomplish cumulative success and development.
