One-Word Substitute: Understanding the Hedonist

The question asks for a single word that means "A person who has a strong belief that pleasure is the chief god". Let's break down the meaning and examine the options.

Defining the Core Concept

The phrase describes someone whose primary life philosophy revolves around the pursuit of pleasure. They believe that experiencing enjoyment and happiness is the most important goal or the highest good in life.

Analyzing the Options

• Doctor: This refers to a medical professional trained to treat illness and injury. It has no relation to beliefs about pleasure.
• Hedonist: This term specifically describes a person who believes that pleasure is the most important aim in life. This aligns perfectly with the given phrase.
• Worshiper: This refers to someone who shows reverence or adoration, typically towards a deity. While pleasure might be sought, the core meaning is about devotion, not necessarily pleasure as the 'chief god'.
• Almighty: This term describes a being with unlimited power, usually referring to God. It is not used to describe a person's life philosophy regarding pleasure.

Conclusion

Based on the definitions, the word that accurately serves as a one-word substitute for "A person who has a strong belief that pleasure is the chief god" is Hedonist.

Therefore, the correct option is the one that defines a Hedonist.
