The phrase “Knowledge is power.” is widely attributed to Sir Francis Bacon, an English philosopher, scientist, and statesman from the late 16th and early 17th centuries. The exact Latin phrase “Scientia potentia est” (meaning “knowledge is power”) is often linked to his works, though the precise wording does not appear in his writings.

Origins and Meaning

• Attributed to: Sir Francis Bacon (1561–1626)
• Earliest Written Form: The idea is found in Bacon’s 1597 book Meditationes Sacrae (Sacred Meditations), where he writes:
  • “Ipsa scientia potestas est.” (Knowledge itself is power.)
• Context: Bacon emphasized the power of knowledge in advancing human progress, particularly in science and governance.

Other Possible Sources

1. Thomas Hobbes (1588–1679) – In Leviathan (1651), Hobbes, who was Bacon’s secretary at one point, wrote:
   • “The Sciences, are small Powers; because not eminent, and therefore not acknowledged in any man; nor are at all, but in a few; and in them, but of few things. But yet, because they are knowledge, they are greater than they seem, because all power is of knowledge…”
   • This suggests he built upon Bacon’s ideas.
2. Biblical or Ancient Influence? – Some scholars believe the idea traces back even earlier, such as in Proverbs 24:5:
3. “A wise man is strong; yea, a man of knowledge increaseth strength.”

Modern Usage and “Health Proverb” Connection

• The phrase “knowledge is power” is often used in education, business, and science.
• As a health proverb, it likely refers to how having knowledge about health (nutrition, hygiene, disease prevention) empowers people to make better choices for well-being.
• This idea aligns with modern public health movements: Educating people about health risks and prevention leads to better outcomes.
