The popularity of Stoicism in recent years has seen it become the subject of bestselling books and internet articles.
While there is much wisdom to be found in Stoic philosophy, it is not without its downsides. The Stoics counseled against worldly attachments of any kind, including friends and family, which can lead to a lack of love and connection with others. Stoics were also proponents of self-sufficiency, meaning dependence on others was seen as a weakness. However, sociopolitical animals like humans require social interaction and cooperation to flourish. The Stoic approach of detachment from everything may not be the best way to value things, particularly when it comes to the relational aspect of being human. Finally, while Stoicism advises detachment from things that can cause pain, it may miss the point that love is a pain knowingly accepted and that suffering may be worth it for the love that has gone before.
