Best of All Possible Blog PostsPosted: March 20, 2020 | |
Aside from his work in mathematics–and lending his name to a brand of butter cookie–Gottfried Wilhelm Leibniz is best known for his philosophical optimism. He opined that ours is the best of all possible worlds. To oversimplify:
1. God, being good, chose to create the best world.
2. God, being omniscient, was able to evaluate all of the infinite facts and truths of all of the infinite possible universes to determine which is most perfect.
3. God, having determined to make the best possible world and having determined which world that would be, created this world.
Like God, people always act in pursuit of good. As Leibniz wrote in his Discourse on Metaphysics, God’s first decree on human nature “is that men should always do, although freely, that which appears to be the best.” This tracks with Aristotle’s claim at the beginning of his Nicomachean Ethics that “every action and pursuit is thought to aim at some good.”
Unlike God, however, people are not omniscient, and therefore cannot infallibly determine what is best. “Each soul knows the infinite, knows all, but confusedly. As in walking on the sea-shore and hearing the great noise that it makes, I hear the individual sounds of each wave, of which the total sound is composed, but without distinguishing them.” Consequently, although we always act in the way that appears best, we very often misjudge what is best and/or how to achieve our objective. Without perfect knowledge of what is best, we “must often be content with the simple twilight of probability.”
So what can we do to improve our probability of identifying what is best and most accurately aiming our actions toward it?
One possibility (not suggested by Leibniz, to my knowledge) is to conserve rational energy by minimizing unnecessary decision-making. Have you ever come home from a particularly difficult day at work and felt like you simply could not decide what to have for dinner? This all-too-common experience is the result of an important reality: decision-making takes energy. And rational energy is limited. If you spend all day making important business decisions or solving problems, it shouldn’t be surprising if, at the end of the day, you lack the energy to make even mundane choices such as what to eat.
By reducing the number of choices one must make in a day, one may conserve some of that precious decision-making energy. Supreme Court Justice David Souter famously ate the same lunch every day: yogurt and an apple. Steve Jobs’ constant turtleneck and jeans combination was part of a conscious effort to reduce decision fatigue. By eliminating trivial decisions, one frees up brain power for more important issues. Hopefully, by saving mental energy, we can make the best possible decisions in this best of all worlds.
Beer of the week: Alter Ego – Some people even drink the same beer all of the time. Once you know what you like, why not stick with it? No regular reader will be surprised to know that I enjoy the decision-making that goes into picking what beer to drink. So even though I have had various “go-to beers” over the years, I would never commit to a single brew for long. Alter Ego is a hazy, orangish IPA from Tree House Brewing Company. Its rocky head hangs around for quite a while. The aroma is quite fruity, and the flavor is of tropical fruit with a decent malt body.
Reading of the week: A Letter of Leibniz – In this excerpt, Leibniz uses two synchronized clocks as a metaphor for how one’s soul and body can be perfectly in sync, even though physical and non-physical bodies cannot act on each other. In typical Leibniz style, he ends the passage with the claim that he has more profound proofs, but the clock metaphor will suffice.
Question of the week: Were Leibniz and Aristotle correct in asserting that every human act is aimed at some good?
