it’s a fact: the future is always uncertain, no matter how much we try to plan for it or predict it. And that uncertainty can easily upset people, because it’s always a possibility that the future won’t go as we want it to. For philosophers of Stoicism, though, uncertainty isn’t something to be frightened of; it’s instead something to be embraced, and to accept as a natural part of the world we live in.

Because uncertainty provides such a large part of the anxiety that people experience, there are numerous Stoic quotes to be found about uncertainty, not knowing what the future will bring, and anxiety about tomorrow’s imagined troubles. For Stoics, it’s clear that the unknown future isn’t what really makes us upset; rather, it’s our opinions about uncertainty that generate most of our anxieties.
