A Guide to the Good Life: The Ancient Art of Stoic Joy

by William B. Irvine

What does it mean to live each day as if it were our last? Some people assume that it means living wildly and engaging in all sorts of hedonistic excess. After all, if this day is our last, we will not pay any price for our riotous living. We can use drugs without fear of becoming addicted. We can likewise spend money with reckless abandon without having to worry about how we will pay the bills that will come to us tomorrow. This, however, is not what the Stoics had in mind when they advise us to live as if today were our last day. To them, living as if each day were our last is simply an extension of the negative visualization technique: As we go about our day, we should periodically pause to reflect on the fact that we will not live forever and therefore that this day could be our last. Such reflection, rather than converting us into hedonists, will make us appreciate how wonderful it is that we are alive and have the opportunity to fill this day with activity. This in turn will make it less likely that we will squander our days. In other words, when the Stoics counsel us to live each day as if it were our last, their goal is not to change our activities but to change our state of mind as we carry out those activities. In particular, they don’t want us to stop thinking about or planning for tomorrow; instead they want us, as we think about and plan for tomorrow, to remember to appreciate today.

Negative visualization, in other words, teaches us to embrace whatever life we happen to be living and to extract every bit of delight we can from it. But it simultaneously teaches us to prepare ourselves for changes that will deprive us of the things that delight us. It teaches us, in other words, to enjoy what we have without clinging to it.

When angry, says Seneca, we should take steps to “turn all [anger’s] indications into their opposites.” We should force ourselves to relax our face, soften our voice, and slow our pace of walking. If we do this, our internal state will soon come to resemble our external state, and our anger, says Seneca, will have dissipated.
