The history of philosophy is normally divided into three periods: Ancient philosophy, medieval philosophy, and Modern philosophy.
To give a thorough list of the main branches of philosophy is difficult, because there have been dissimilar, equally acceptable divisions at different times, and the division are often relative to the concern of a particular period. However, the following branches are usually established as the main ones.
* Metaphysics investigate the nature of being and the world. Usual branches are cosmology and ontology.
* Epistemology is concerned with the nature and scope of awareness, and whether knowledge is achievable. Among its central concern has been the challenge posed by skepticism and the relationships among truth, belief and justification.
* Ethics, or 'moral philosophy', is concerned with questions of how persons ought to act or if such question are answerable. The major branches of ethics are meta-ethics, normative ethics and applied ethics.
* Political Philosophy is the study of government and the association of individuals and communities to the state. It includes question about law, property, and the rights and obligation of the citizen.
* Aesthetics deal with beauty, art, enjoyment, sensory-emotional values, perception, and matters of taste and response.
* Logic deals with pattern of thinking that lead from true premises to true conclusion. Beginning in the late 19th century, mathematicians such as Frege began a mathematical action of logic, and today the subject of logic has two broad divisions are mathematical logic and what is now called philosophical logic.
* Philosophy of Mind deals with the natural world of the mind and its relationship to the body, and is typified by disputes among dualism and materialism. In recent years there is an increasing link between this branch of philosophy and cognitive discipline
* Philosophy of language is the reasoned query into the nature, origins, and usage of language.

Popup campers are trivial, aerodynamic trailers that can be towed by a small car, such as the BMW Air Camper and the Coleman Bayside. They are built to be shorter than the tow vehicle, minimizing drag.
Others range from two-axle campers that can be pulled by most mid-sized pickups to trailers that are as long as the host country's law allows for drivers without individual permits. Larger campers tend to be fully integrated leisure vehicles, which often are used to tow single-axle dolly trailers to allow the driver to bring small cars on their travels.
