Plutarch, On Awareness Of Progress In Virtue - Problems With Stoic Views - Sadler's Lectures
This lecture discusses key ideas from the ancient Middle Platonist philosopher and biographer Plutarch's essay On Awareness Of Progress In Virtue
This episode focuses specifically on his criticisms of the standard Stoic position on virtue and vice, which is that every person is either virtuous or vicious, with no middle state. The Stoics (with some exceptions like Epictetus) also seem to think that there is no such thing as "making progress" towards virtue and away from vice.

Francis Bacon, Novum Oraganum - The Idols Of The Theater - Sadler's Lectures
This lecture discusses key ideas from the early modern philosopher Francis Bacon's work Novum Organum, specifically the section in book 1 covering the "four idols of the human mind"
This episode focuses specifically on his description of the fourth type of idol, those of the theater, which derive from either entire philosophical systems, which Bacon likens to fictions and plays, or from perverted rules of demonstration, or from too exclusive of a focus on one aspect or element of a science. Bacon divides the three kinds of philosophies he criticizes into sophistic (exemplified by Aristotle), empiric, and superstitious or theological (exemplified by Plato).

This lecture discusses key ideas from the ancient Middle Platonist philosopher and biographer Plutarch's essay On Tranquility

Foolish people don't appreciate the present, because they focus too much on the future that may never come about.

The wise live a life that integrates past and present productively as they move into the future.
