Questions this course answers

What does Moore mean by saying that good is indefinable?

Moore distinguishes a simple ethical quality from complex things that can be analyzed into parts.

What is the open-question argument meant to show?

If good meant pleasant, asking whether something pleasant is good would be a closed, merely verbal question; Moore says it remains substantive.

What is Moore’s target in the naturalistic fallacy?

Moore allows facts about consequences to matter while rejecting the identification of a natural description with goodness itself.

How does Moore distinguish hedonism from his own ideal theory?

Moore argues that valuable consciousness can include more than agreeable sensation and depends on its objects and relations.

What is an organic whole?

Moore says context and structure can change how the value of a complete state of affairs compares with the value of isolated elements.

What criterion does Moore propose for right conduct?

In the conduct chapters Moore turns intrinsic value into a consequentialist test, while acknowledging the practical role of ordinary rules.
