Examples of principles are, entropy in a number of fields, least action in physics, those in descriptive comprehensive and fundamental law doctrines or assumptions forming normative rules of conduct, separation of church and state in statecraft, the central dogma of molecular biology, fairness in ethics, etc. In common English, it is a substantive and collective term referring to rule governance, the absence of which, being unprincipled, is considered a character defect.

The law establishes a legal obligation, in a coercive way it therefore acts as principle conditioning of the action that limits the liberty of the individuals. See, for examples, the territorial principle, homestead principle, and precautionary principle. As scientific laweditArchimedes principle, relating buoyancy to the weight of displaced water, is an early example of a law in science. Another early one developed by Malthus is the population principle, now called the Malthusian principle. Freud also wrote on principles, especially the reality principle necessary to keep the id and pleasure principle in check. Biologists use the principle of priority and principle of Binominal nomenclature for precision in naming species. There are many principles observed in physics, notably in cosmology which observes the mediocrity principle, the anthropic principle, the principle of relativity and the cosmological principle. Other well known principles include the uncertainty principle in quantum mechanics and the pigeonhole principle and superposition principle in mathematics. As axiom or logical fundamenteditPrinciple of sufficient reasoneditThe principle states that every event has a rational explanation. The principle has a variety of expressions, all of which are perhaps best summarized by the following For every entity x, if x exists, then there is a sufficient explanation for why x exists. For every event e, if e occurs, then there is a sufficient explanation for why e occurs. For every proposition p, if p is true, then there is a sufficient explanation for why p is true. However, one realizes that in every sentence there is a direct relation between the predicate and the subject. To say that the Earth is round, corresponds to a direct relation between the subject and the predicate. Principle of non contradictioneditAccording to Aristotle, It is impossible for the same thing to belong and not to belong at the same time to the same thing and in the same respect. For example, it is not possible that in exactly the same moment and place, it rains and doesnt rain. Principle of excluded middleeditThe principle of the excluding third or principium tertium exclusum is a principle of the traditional logic formulated canonically by Leibniz as either A is B or A isnt B. It is read the following way either P is true, or its denial P is. It is also known as tertium non datur A third thing is not. Classically it is considered to be one of the most important fundamental principles or laws of thought along with the principles of identity, no contradiction and sufficient reason.
