Confucius-Buddha-TouchstoneTruth

Are Buddhist or Confucian teachings closer to their original meaning?

2Science >

Timbre is the unique "tone color" of an instrument or voice, resulting from its fundamental frequency (measured in hertz) and harmonic overtones. It's the distinctive blend of base tones and overtones that gives each instrument its recognizable voice, beyond just pitch (e.g., A4 at 440 Hz).

What is the nature of timbre?

3Critical Thinking >

A false cause fallacy assumes that one event directly causes another without proof. It links two events improperly, ignoring other factors, often leading to flawed conclusions based on coincidence, not causality.

Quote of the Week
“Being and non-being create each other.”
  • Laozi
  • 550 BCE
Daoism
TAKE-AWAY: Opposites are interconnected and mutually dependent. In Daoism, contrasting forces like existence and non-existence, light and dark, or high and low, all rely on each other for meaning. Laozi teaches that balance and harmony are found when we recognize that these dualities are not in conflict but are essential to the natural order of life.
