Inquiry

Inquiry is a formal process used to increase knowledge, resolve doubt, or solve specific problems. It is more than just asking a question. It is a structured way of thinking that helps move a person from a state of uncertainty to a state of belief. This state of belief is often referred to as knowledge or certainty.

Philosophers have developed various theories of inquiry to explain how these processes work. These theories describe how different types of reasoning achieve their specific aims.

One of the most important ways to understand inquiry is through three modes of reasoning: abduction, deduction, and induction. These three modes often function in a continuous cycle. Abduction is used to generate a likely hypothesis or an initial diagnosis when a problem is first noticed. Once a hypothesis is formed, deduction is used to clarify its consequences and explain what should follow if the guess is correct. Finally, induction is used to test those specific predictions against real-world data.

This cycle systematically reduces uncertainty and leads to an increase in skills and knowledge.

Each mode of reasoning has a very different character. Deduction is considered an exact or demonstrative form of inference. This means that if the starting rules and cases are true, the conclusion must also be true. It is a purely internal process of the mind. In contrast, abduction and induction are approximate or non-demonstrative. They are not always exact because they require constant interaction with the outside world.

Because the outside world is so vast, these methods involve elements of fallible judgment and can lead to error.

Aristotle provided the classical foundation for these ideas in his work, "Prior Analytics." He described the mechanics of how terms relate to one another. In deduction, he noted that if one term is contained within a middle term, and that middle term is contained within another, a perfect syllogism is formed. For example, if A applies to all B, and B applies to all C, then A must apply to all C.

He also described induction as establishing a relation between an extreme term and a middle term through another extreme. His work on abduction suggested that we can move closer to knowledge by introducing intermediate terms.

Much later, the pragmatic philosophers refined these classical ideas. Charles Sanders Peirce, William James, and John Dewey studied inquiry as a way to address the nature of scientific reasoning. Peirce specifically extracted these ideas from classical logic and the work of Immanuel Kant. He helped show that abduction, deduction, and induction are not isolated tools. Instead, they are parts of a whole system where each part relies on the others.

For instance, an abduction is only useful if it produces a guess that deduction can explain and induction can evaluate.

John Dewey offered a unique definition of this process. He described inquiry as the controlled transformation of an indeterminate situation. An indeterminate situation is one that is confusing or lacks clear connections. Through inquiry, this situation becomes determinate, meaning its parts are organized into a unified whole.

Dewey and Peirce also recognized that inquiry is not just a private mental act. They saw it as a social process, a concept often called a "community of inquiry."

While inquiry is a powerful tool, some thinkers have discussed its potential limits. Charles Sanders Peirce argued that inquiry moves indefinitely toward a limit he called "truth." Other traditions suggest ethical or boundaries to what should be asked. For example, some Jewish rabbinical writers interpreted the text of Deuteronomy to suggest limits on inquiry. They reasoned that while one may ask about the days of creation, one should not inquire about what exists before creation or what lies beyond the universe. These different perspectives show the deep complexity of how humans approach the unknown.
