Meaning is an intention, aim, or design. When we say we want to know what life means, we are really saying we want to know what it s for. Well, the primary feature of life is intelligence. By intelligence we mean purposeful activity. We make decisions and do things.
Parameciums make decisions and do things.
Rocks do not make decisions, although they can chip a tooth. If we knew why we have intelligence, we would be a great deal closer to understanding why we do anything, including exist. To understand intelligence, we must understand the mind. Science has given us many answers, but the one thing that science is still completely silent about is the nature of consciousness. Of course, there is more and more information every day about the connection between consciousness and the brain.
