The Five Great Philosophies of Life" by William de Witt Hyde begins with a description of Epicureanism and Stoicism. Here is how the author describes them.
The Epicurean seeks simple, attainable pleasures. Not excessive consumption, but enjoying day to day living, even while taking it slow, not "over-working", but spending time with friends and simple pleasures, and -- using the author's updated example -- hanging around one's club, socializing, and not doing much more. Even though its advocates were advised not to seek out ambitious material and political goals, the philosophy is essentially materialistic: since happiness comes not from any abstract sense of purpose, nor from aiding a divine end, but from achievable, material goals.
In contrast, Stoicism looks beyond man, seeing him as part of a universal mechanism. Instead of seeking small pleasures, stoicism critiques the nature of emotions by saying that even when we do not control what happens around us, we can completely control how we feel. External states do not necessitate particular mental states [we hear this echo in Christian Science]. Like Epicureans, Stoics too sought human happiness, but they thought it came less from material things than from our selves: our evaluations and our ability to be untroubled by travails.
After these two summaries, the author goes back in time to Plato and Aristotle. This anti-chronological treatment is a bit confusing, but it allows the author to lay down a basis before showing that Plato and Aristotle had a better approach than the Stoics or Epicureans.
He praises Plato for advocating reason, and for pointing out that concrete things are not good or evil outside of a context. One has to look to the larger purpose. Means serve ends, but those ends are usually the means to other ends. We have to trace this chain to know if the original means serves the good. When tracing thus, Plato does not stop at the individual human, but sees the individual as a part of society, who ought to serve that society as a body part ought to serve the individual. Though Plato does not criticize appetite, he does give it short shrift because he is so focused on ever remote ends (hence "Platonic love' is well-named).
Aristotle turns back the view toward the individual. He sees pleasure as a sign of good function, but his view would not fit with Epicureans who put much more focus on material pleasure. Aristotle might have viewed their approach as an attempt to reverse cause and effect. He would be even less compatible with the Stoic subordination of the individual to the universal, and he rejected asceticism. His was fundamentally an individualistic and practical outlook ("We acquire virtues by doing the acts"). Like Plato, he agreed that values were contextual: i.e. with things being good, depending on the context. From this comes the "Aristotelian mean" which is not meant to be an average, but a "right amount".
The author is a modernized christian. He has led up to Aristotle as being the best of the four, and then goes on to add Christianity as the fifth, and the final perfect addition to Aristotle. The author's version of Christianity rejects the asceticism of some early denominations, and rejects most church-created procedures. We must not even do things that Jesus might have done, he says, if those are concretes or just customs of the time. Even being our brother's keeper might require sternness and "teaching a man to fish" rather than in giving hand-outs. What, then, does Christianity add to Aristotle? In de Witt's view, it adds: love (as in "love they neighbor"). So, we do not have Plato's outright communism where every man lives primarily for the community, but instead we have each man living for himself, but with love for his neighbors, thus forming a community.
Summary: A well-written overview of the four ancient philosophies. In each section, the author first presents the philosophy with quotes to support his views, and attempts to argue for the positives. Then, he presents his critique. The fifth section (on Christianity) can be skipped with little loss.
