From each of our perspectives, our own
lives are extremely important. We compulsively check our phone or email accounts
for that life-changing message (“did I get accepted or not?”), and we celebrate
accumulating 1000 “friends” on Facebook (“I’m probably the most connected
person I know!”).
Yet, from an objective, third-person,
perspective, e.g. the point of view of the universe, our lives seem to be
meaningless. No matter what we accomplish in our lives, it seems like our
actions will have no discernable impact on the universe as a whole. You may
have already given up hope of being a famous singer or sports star. Maybe you
are striving to be a scientist, so that you can cure cancer or discover a new renewable
energy source. But, from the universe’s point of view, even these esteemed
careers and achievements will not earn you a meaningful life.
Thomas Nagel and others have discussed this
absurd contrast between how meaningful and significant our lives are from the
inside when compared to an objective viewpoint (usually referred to as the
absurd). Nagel would have us embrace the irony of the situation and enjoy a
cosmic giggle at our own expense. Of course, many religions provide
explanations for our Earthly existence that resolve this absurdity. For
example, eternal reunification with the creator of the universe might be
offered as a reward for an Earthly life well lived.
The absurd, then, is only a potential cause
for concern in the non-religious people who cannot find humour in the meaninglessness
of their lives apparent from an objective perspective. Leo Tolstoy, as
recounted in his My Confession, was
in this situation. Tolstoy was a beloved family man, famous author, and wealthy
landowner. Despite these advantages, Tolstoy became paralyzed by the objective
meaninglessness of his life. He questioned the ultimate significance of his
actions, but could not find any satisfying answers.
Based on a firm belief in science as the
method for learning about the universe, Tolstoy was convinced that the universe
would eventually die and that all humans and their legacies would be completely
annihilated. As a result, he believed that it was impossible for him to leave
his mark on the universe. In his words, and from his scientific outlook, he
thought it impossible to connect our finite lives with something infinite or
permanent.
Just when Tolstoy was about to abandon all
hope of breaking out of his paralyzing depression, he realized that the vast
majority of people did not share his dismal view of life. Recognizing that it
was religious faith that allowed others to feel connected to something
infinite, Tolstoy buried his earlier opinion of religion as “monstrous” and
became a Christian of sorts. Fortunately for Tolstoy, this enabled him to break
free from the grip of the absurd.
What I’d like to do here is propose a
naturalist account of the meaning of life that could have provided Tolstoy with
another option (and provides another option for anyone currently in the
situation he was in). As such, this account is only intended to appeal to people
who don’t believe in Gods and souls, and find the absurd distressing.
I call the account Optimistic Naturalism,
and it entails belief in these two principles:
Infinite Consequence: performing an action that has infinite consequences for life is sufficient to confer True Meaning on the life of the actor, if the actor finds those particular infinite consequences to be subjectively meaningful (in part) because they are infinite.
Scientific Optimism: continual scientific and technological advancement might allow our actions to have infinite consequences for life in a purely physical universe.
Following Susan Wolf’s view of the
important kind of meaning, I take True Meaning to mean the meaning that arises
from the right kind of connection between the subjective and objective points
of view. For example Infinite Consequence is the view that performing an action
that has infinite consequences for life is sufficient to confer True Meaning on
the life of the actor, if the actor finds those particular infinite
consequences to be subjectively meaningful (in part) because they could be
infinite. For example, if I develop a technology that enables humans to avoid
the supernova of our sun, and I find this meaningful partly because I believe
it will help enable life to continue for infinity, then, if life does persist
continuously, I will have lived a truly meaningful life.
Here is a brief defence of the main
principles.
Is having an infinite consequence really
objectively meaningful? First, realize that most objective viewpoints are
multi-subjective standards, which are unavoidably tainted by the socio-cultural
values of the individuals involved. By taking our standard as the point of view
of the universe, we can step back until all residue of subjective value has
disappeared. Our finite lives and legacies become so small from this vantage
point that they pale into insignificance. But, infinite consequences are not
quite like this. No matter how far we step back, and no matter how distant the
objective viewpoint is, infinite consequences will never vanish into
insignificance. When all the values and finite consequences have disappeared
into the distance, actions with infinite consequences remain, ineluctably
influencing future events.
Is Scientific Optimism too optimistic? How
can we avoid the big chill (when the universe effectively becomes inert)? One
live theory in cosmology, Eternal Inflation, predicts that new parts of the
universe will always bubble out from our existing one. If this theory is
correct, then the right kinds of advanced technology might enable some form of
life to escape into new parts of the universe whenever the existing parts are
becoming uninhabitable and thereby persist for infinity. Of course, great
advances in science and technology would be required to enable us to take
advantage of these ‘bubbles’ in this way. But, until recently, humans couldn’t
even fly, and now we can fly to space and back!
