12. analogy การเปรียบเทียบ
An analogy is a similarity between things.
In an argument from analogy, one argues from
known similarities to further similarities. Such
arguments often occur in philosophy. In his Dialogues
Concerning Natural Religion, David Hume
considers an argument from analogy that purports
to show that the universe was created by an
intelligent being. The character Cleanthes claims
that the world as a whole is similar to things like
clocks. A clock has a variety of interrelated parts
that function together in ways that serve ends.
The world is also a complex of interrelated parts
that function in ways that serve ends, such as providing
food for human consumption. Clocks are
the result of intelligent design, so, Cleanthes concludes,
probably the world as a whole is also the
product of intelligent design. Hume’s character
Philo criticizes the argument. In “The Argument
from Analogy for Other Minds,” Bertrand Russell
uses an argument from analogy to try to justify
his belief that other conscious beings exist.
