Ethics is not subjective

Thinking that ethics is subjective creates bad arguments.

People use the word subjective - and objective - in ways that lead to confusion, misguided conclusions, and failed attempts to convince someone that ethics matters. Thinking carefully about distinctions and words and concepts enables us to see the world more clearly, enabling us to draw better conclusions and decisions.

Problem Solving


Many people have stories of achieving something great because someone had high expectations of them. The concept of the Pygmalion Effect is that expectations will influence performance and become a self-fulfilling prophecy.

The term "Pygmalion effect" comes from studies done in the 1960s on the effect of teacher's expectations on students' IQ. If teachers had high expectations, would pupils live up to them? Although the conclusion was that the effects were negligible, the idea is widespread.

The Inevitable Stage In Growth: Plateau

A common motivation dip is the performance plateau, when the quick and easy gains are over and done with, and slowly the momentum to keep your motivation diminishes. This feels like you have reached some sort of limit, and most people take it as a cue to settle down, and consequently stop improving.

Going beyond the plateau of contentment is crucial to hitting big goals.

A first principle is the fundamental building block of an idea, the most indivisible part that we know to be true and that we can use to build more complex thoughts.

Ancient Greek Philosophy
  • Ancient Greek philosophy extends from as far as the seventh century B.C. up until the beginning of the Roman Empire, in the first century A.D.
  • It distinguishes itself from other early forms of philosophical and theological theorizing for its emphasis on reason as opposed to the senses or the emotions.
  • During this period five great philosophical traditions originated: the Platonist, the Aristotelian, the Stoic, the Epicurean, and the Skeptic.
  • Favorite themes include the principle of reality, the good; the life worth being lived; the distinction between appearance and reality, etc.
