Politics are the process and method of gaining or maintaining support for public or common action, the conduct of decision-making for groups. Although it is usually applied to governments, political behavior is also observed in corporate, academic, religious, and other institutions. Political science is the field devoted to studying political behavior and examining the acquisition and application of power, or the ability to impose one's will on another. Its practitioners are known as political scientists. Political scientists look at elections, public opinion, institutional activities (how legislatures act, the relative importance of various sources of political power), the ideologies behind various politicians and interest groups, how politicians achieve and wield their influence, and so on.
The Fourth International has been a communist international organisation working in opposition to both capitalism and Stalinism. Consisting of supporters of Leon Trotsky, it has striven for an eventual victory of the working class to bring about socialism. In Paris in 1938, Trotsky and many of his supporters, having been expelled from the Soviet Union, considered the Comintern to have become lost to "Stalinism" and incapable of leading the international working class towards political power. Thus, they founded their own competing "Fourth International". Throughout the better part of its existence, the Fourth International was hounded by agents of the Soviet secret police, repressed by capitalist countries such as France and the United States, and rejected by followers of the Soviet Union and later Maoism as illegitimate - a position these communists still hold today. The FI suffered a split in 1940 and an even more significant split in 1953. Despite a partial reunification in 1963, more than one group claims to represent the political continuity of the Fourth International. The broad array of Trotskyist Internationals are split over whether the Fourth International still exists and if so, which organisation represents its political continuity.
There is a sort of enthusiasm in all projectors, absolutely necessary for their affairs, which makes them proof against the most fatiguing delays, the most mortifying disappointments, the most shocking insults; and, what is severer than all, the presumptuous judgement of the ignorant upon their designs.
