What is Theory? – Scientific Definition




Theory is an idea that is proposed to explain something. It is based on observations and evidence and can be tested through experiments or further observation. A theory has been well-supported by evidence if it has been repeatedly tested and shown to be reliable.

Scientific Theory

A scientific theory is a well-substantiated explanation of an aspect of the natural world that is supported by a body of evidence. In science, a theory is not the same as a hypothesis. A hypothesis is a testable statement about the natural world that can be used to build more complex inferences and explanations.

A scientific theory is much broader in scope and serves to explain and organize a body of evidence that supports it. Theories can be strongly supported by data, but they can also be little more than educated guesses.

Mathematical Theory

A mathematical theory is a set of ideas that explains or predicts something. It is usually based on previous knowledge or observations. A theory can be used to build new knowledge or solve problems.

Mathematical theories are built on a foundation of axioms and definitions. Axioms are basic statements that are assumed to be true. Definitions are used to give meaning to new terms. Theories also use logic and reasoning to develop hypotheses, which are testable predictions about what will happen in certain situations.

Theories can be proven using mathematical proof. Proof is a logical argument that shows that a statement is true. Theories can also be disproven if a counterexample is found, which is an example that contradicts the theory.

Philosophical Theory

A philosophical theory is a belief system that is used to explain the nature of reality and existence. Philosophical theories can be used to describe the physical world, the human mind, and society.


Metatheory is the branch of philosophy that deals with the nature of theory, its presuppositions and basic categories, and the relationships between theories. Metatheory also encompasses the study of how different theories can be integrated into a single framework.

In recent years, there has been a growing recognition of the importance of metatheory in the social sciences. This is due in part to the fact that social scientists are increasingly working across disciplinary boundaries, and therefore need to be able to compare and contrast different theoretical approaches.

Political Theory

In political science, a political theory is a set of ideas that explains how the world works. It is used to make sense of the world around us and to make predictions about what will happen in the future. Political theories can be divided into two main types:

  • Normative
  • Positive

Normative Theories

Normative theories are concerned with what should be, while positive theories are concerned with what is. Normative theories often take the form of ethical or moral arguments about how the world ought to be governed.

Positive Theories

Positive Theories, on the other hand, focus on describing how the world actually works. Both types of theory are important in political science. Positive theories help us to understand how the world works, while normative theories help us to decide what kind of world we want to live in.

Jurisprudential Theory

Jurisprudential theory is a branch of philosophy that deals with the nature of law and its relation to society. It asks questions such as: What is law? What is its purpose? How does it work?

Jurisprudential theory has been divided into two main schools of thought:

  • Natural Law
  • Legal Positivism

Natural Law

Natural law theorists believe that there is a universal, objective morality that can be discovered through reason.

Legal Positivism

Legal positivists, on the other hand, believe that morality has no place in the study of law; they focus instead on the positive laws enacted by legislatures or courts.

Example of Theory

An example of a scientific theory is Darwin’s Theory of Evolution. This theory explains how species change over time and how new species are created. It is supported by evidence from many different fields, including paleontology, genetics, and biology.

Another example of a scientific theory is Einstein’s Theory of Relativity. This theory explains the behavior of objects in space and time
