I can't speak for others, but I find the fundamental idea that a life worth living is one during which one strives every day to become a better person to be compelling.

Given the power and influence that science increasingly has in our daily lives, it is important that we as citizens of an open and democratic society learn to separate good science from bunk. This is not just a matter of intellectual curiosity, as it affects where large portions of our tax money go, and in some cases even whether people’s lives are lost as a result of nonsense.

What the world needs is more compassion; love in the broad sense, and use of practical reason to solve human problems. What it needs less is ideological and religious fanaticism, of which, unfortunately, there currently is aplenty.

If a theory purports to explain everything, then it is likely not explaining much at all.

Death itself is a natural occurrence, it is unavoidable, and the Stoics thought that part of philosophical practice is to get comfortable with the unavoidable, learning to face it with courage.

I don't see any Stoic practice as problematic or risky, but I would advise to engage in extreme versions of the negative visualization exercise only if you are an advanced practitioner. The negative visualization is a meditation during which you visualize, slowly and deliberately, something bad or discomforting happening to you.

"Fate permitting" is a standard Stoic phrase meant to remind ourselves that planning things is up to us, but the ultimate outcomes are not under our control. It helps us to develop an attitude of equanimity toward the universe. We should very much try to change things for the better, that's the whole point of the Stoic discipline of action.
