Introduction

Human existence is deeply tied to light, which has enabled much of our progress. Historically, light has symbolized “good” and darkness “evil,” echoing philosophies like Yin and Yang. This article examines morality through light, seeing it as a spectrum of both the objective “good” and the subjective.

From Ancient Illumination to Electromagnetic Waves

The emergence of light transformed humanity as we know it. Since our origin, the perception of the sunrise, the reflection of the moon, the twinkle of the stars, and even the flicker of fireflies has shaped our species. These natural phenomena regulated our cycles of labour and rest, as well as our progression in constructing systems of ethics regarding good and evil. Historically, darkness was seen as a symbol of the somber, the malevolent, and the destructive. The Homo erectus’s discovery of fire through friction introduced the first man-made light. This evolved through the civilizations of Mesopotamia, Syria, and Egypt, which developed lighting systems based on oil lamps, a technology that persisted until the 19th century. This era saw a dual revolution: Thomas Edison developed the incandescent bulb, while Max Planck discovered that light is composed of discrete packets of energy called quanta. This eventually revealed the dual nature of light, behaving as both a particle and a wave.

The Universality of Light within Individualism

The conception of a conscious and unified humanity gained momentum in the 4th century B.C., as it was realized that all humans possess a similar perception of morality. Light became recognized as a universal “good,” just as the concepts of good and evil were found to exist across all ethnicities, what would later be defined as the moral conscience. However, the 18th-century race for electricity and light shifted the balance of power. The control of the world fell into the hands of those who mastered these sectors. Thus, light which possessed the potential to unite began to divide. In this context, “evil” gained ground through the human propensity to imitate destructive behaviours. As humanity segregated into universal power blocks, a frantic race toward capitalism and materialism emerged, seeking self-satisfaction and joy through the accumulation of money and power.

The Unity of Light within Pluralism

Light’s association with the collective has been upheld by those who embody the “Good,” showing that humanity exists through morality. Among moral figures, Buddha stands out: through 49 days of meditation, he found inner peace and detachment from materialism, teaching that spiritual light counteracts the darkness of greed, desire, and suffering.

Conclusion

Light has brought both great benefits and responsibilities, revealing the duality of good and evil and shaping forces that unite and divide us. Since the 18th century, capitalism and materialism have thrived on mastering light, yet individuals like Buddha and Gandhi show that ethical mastery of light is essential to guiding humanity.
