You Don't Need a Meaning of Life to Have a Meaningful Life

Like fairness, perception of meaning has neural correlates.  It would be a logical fallacy to conclude that there's a 'Meaning of Life' just because we have evolved the capacity to perceive meaning.

Therefore, you don't need a 'Meaning of Life' to have a meaningful life; a life full of meaning.  Reflecting, another skill/dynamic of the mind, on the probability of life in the universe is sufficient to conclude that the life we do have is 'special'; or at least rare.  All the more special with the knowledge that death terminates one's possible, but low probability life.

The same mental dynamics that result in 'meaning' are also making great strides in revealing the origin's of life:
