Truth is most often used to mean in accord with fact or reality, or fidelity to an original or to a standard or ideal.
The commonly understood opposite of truth is falsehood, which, correspondingly, can also take on a logical, factual, or ethical meaning. The concept of truth is discussed and debated in several contexts, including philosophy and religion. Many human activities depend upon the concept, which is assumed rather than a subject of discussion, including science, law, and everyday life.
Philosophical logic refers to those areas of philosophy in which recognized methods of logic have traditionally been used to solve or advance the discussion of philosophical problems. Sybil Wolfram lists the study of argument, meaning, and truth in particular, while Colin McGinn includes identity, existence, predication, necessity, and truth as the main topics of his book on the subject. In the same vein, philosophical logic is often understood to address extensions and alternatives to classical logic—the so-called non-classical logics. Texts such as John P. Burgess' Philosophical Logic, the Blackwell Companion to Philosophical Logic, or the multi-volume Handbook of Philosophical Logic (edited by Dov M. Gabbay and Franz Guenthner) emphasize this latter usage, addressing both the formal aspects of these topics and their applications to associated philosophical problems.

Political philosophy is the study of such topics as politics, liberty, justice, property, rights, law, and the enforcement of a legal code by authority: what they are, why (or even if) they are needed, what, if anything, makes a government legitimate, what rights and freedoms it should protect and why, what form it should take and why, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever. In a vernacular sense, the term "political philosophy" often refers to a general view, or specific ethic, political belief or attitude, about politics that does not necessarily belong to the technical discipline of philosophy. In short, political philosophy is the activity, as with all philosophy, whereby the conceptual apparatus behind such concepts as aforementioned are analyzed, in their history, intent, evolution and the like.
A double-barreled question (sometimes, double-direct question) is an informal fallacy. It is committed when someone asks a question that touches upon more than one issue, yet allows only for one answer. This may result in inaccuracies in the attitudes being measured for the question, as the respondent can answer only one of the two questions, and cannot indicate which one is being answered.
Many double-barreled questions can be detected by the existence of the grammatical conjunction "and" in them. This is not a foolproof test, as the word "and" can exist in properly constructed questions.

A social issue (also called a social problem, societal ill, social ill, or social situation) is an issue that relates to society's perception of a person's life, moral character, occupation, etc.. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
