Infinite means without end so an infinite person would be someone who is limitless or without end. Historical and religous figures may be considered infinite in the sense that they continue to have an impact on socieity while they are alive and past their death. Some of these can include Jesus, Muhammad whom millions of people follow their beliefs to this day. Sigmund Freud and Skinner are academic historic figures that have had major contributions to their field and are still relevant today well past their death. Even policital figures such as Stalin who have changed the course of history and have had a lasting impact on our world.
