input: Journey's album sales did not improve and Columbia Records requested that they change their musical style and add a frontman, with whom keyboardist Gregg Rolie could share lead vocal duties. The band hired Robert Fleischman and transitioned to a more popular style, akin to that of Foreigner and Boston. Journey went on tour with Fleischman in 1977 and together the new incarnation of the band wrote the hit "Wheel in the Sky"; however, management differences resulted in Fleischman leaving within the year. In late 1977, Journey hired Steve Perry as their new lead singer. Herbie Herbert, the band's manager, also hired Roy Thomas Baker as a producer to add a layered sound approach as Baker had done with his previous band, Queen. With their new lead singer and talented new producer, Journey released their fourth album, Infinity (1978). This album set Journey on their road to stardom with their first RIAA-certified platinum album. This album, with their hit song "Wheel in the Sky" (#57 U.S.), set Journey on a new path with a more mainstream sound to make their highest chart success to date. In late 1978, manager Herbie Herbert fired drummer Aynsley Dunbar, who joined Bay Area rivals Jefferson Starship shortly thereafter. He was replaced by Berklee-trained jazz drummer Steve Smith. Perry, Schon, Rolie, Smith and Valory recorded Evolution (1979), which gave the band their first Billboard Hot 100 Top 20 single, "Lovin', Touchin', Squeezin'" (#16); and Departure (1980), which reached No. 8 on the album charts. Journey's newfound success brought the band an almost entirely new fan base. During the 1980 Departure world tour, the band recorded a live album, Captured. Keyboardist Gregg Rolie then left the band, the second time in his career he left a successful act. Keyboardist Stevie "Keys" Roseman was brought in to record the lone studio track for Captured, "The Party's Over (Hopelessly in Love)," but Rolie recommended pianist Jonathan Cain of The Babys as the permanent replacement. With Cain's replacement of Rolie's Hammond B-3 organ with his own synthesizers, the band was poised for a new decade in which they would achieve their greatest musical success.

input: Rawls derives two principles of justice from the original position. The first of these is the Liberty Principle, which establishes equal basic liberties for all citizens. 'Basic' liberty entails the (familiar in the liberal tradition) freedoms of conscience, association and expression as well as democratic rights; Rawls also includes a personal property right, but this is defended in terms of moral capacities and self-respect, rather than an appeal to a natural right of self-ownership (this distinguishes Rawls's account from the classical liberalism of John Locke and the libertarianism of Robert Nozick). Rawls argues that a second principle of equality would be agreed upon to guarantee liberties that represent meaningful options for all in society and ensure distributive justice. For example, formal guarantees of political voice and freedom of assembly are of little real worth to the desperately poor and marginalized in society. Demanding that everyone have exactly the same effective opportunities in life would almost certainly offend the very liberties that are supposedly being equalized. Nonetheless, we would want to ensure at least the "fair worth" of our liberties: wherever one ends up in society, one wants life to be worth living, with enough effective freedom to pursue personal goals. Thus participants would be moved to affirm a two-part second principle comprising Fair Equality of Opportunity and the famous (and controversial) difference principle. This second principle ensures that those with comparable talents and motivation face roughly similar life chances and that inequalities in society work to the benefit of the least advantaged. Rawls held that these principles of justice apply to the "basic structure" of fundamental social institutions (such as the judiciary, the economic structure and the political constitution), a qualification that has been the source of some controversy and constructive debate (see the work of Gerald Cohen). Rawls further argued that these principles were to be 'lexically ordered' to award priority to basic liberties over the more equality-oriented demands of the second principle. This has also been a topic of much debate among moral and political philosophers. Finally, Rawls took his approach as applying in the first instance to what he called a "well-ordered society ... designed to advance the good of its members and effectively regulated by a public conception of justice". In this respect, he understood justice as fairness as a contribution to "ideal theory", the determination of "principles that characterize a well-ordered society under favorable circumstances". Much recent work in political philosophy has asked what justice as fairness might dictate (or indeed, whether it is very useful at all) for problems of "partial compliance" under "nonideal theory".
