This article summarizes the roots of analytic philosophy in the logical empiricism of the Vienna Circle, gives a brief notice of its development, and shows its recent pragmatist renewal. Finally, a balance is made of the best achievements of analytic philosophy for the 21st century against the impoverishing scientific naturalism dominant in much of current North American philosophy. In accordance with this, the paper is divided into four sections: 1) a first dedicated to logical positivism of the first decades of the last century; 2) the second destined to make a quick history of analytic philosophy; 3) the third shows the pragmatist renewal of analytic philosophy; and 4) a final part in which a balance is made of the best results of this tradition of thought for the 21st century.
