The idea of Masonic brotherhood probably descends from a 16th-century legal definition of a brother as one who has taken an oath of mutual support to another. Accordingly, Masons swear at each degree to keep the contents of that degree secret, and to support and protect their brethren unless they have broken the law. In most Lodges the oath or obligation is taken on a Volume of Sacred Law, whichever book of divine revelation is appropriate to the religious beliefs of the individual brother (usually the Bible in the Anglo-American tradition). In Progressive continental Freemasonry, books other than scripture are permissible, a cause of rupture between Grand Lodges.
Why are masons allowed to divulge the secrets of each degree?

Another recent environmental issue in Melbourne was the Victorian government project of channel deepening Melbourne Ports by dredging Port Phillip Baythe Port Phillip Channel Deepening Project. It was subject to controversy and strict regulations among fears that beaches and marine wildlife could be affected by the disturbance of heavy metals and other industrial sediments. Other major pollution problems in Melbourne include levels of bacteria including E. coli in the Yarra River and its tributaries caused by septic systems, as well as litter. Up to 350,000 cigarette butts enter the storm water runoff every day. Several programs are being implemented to minimise beach and river pollution. In February 2010, The Transition Decade, an initiative to transition human society, economics and environment towards sustainability, was launched in Melbourne.

Cubist sculpture developed in parallel to Cubist painting. During the autumn of 1909 Picasso sculpted Head of a Woman (Fernande) with positive features depicted by negative space and vice versa. According to Douglas Cooper: "The first true Cubist sculpture was Picasso's impressive Woman's Head, modeled in 190910, a counterpart in three dimensions to many similar analytical and faceted heads in his paintings at the time." These positive/negative reversals were ambitiously exploited by Alexander Archipenko in 191213, for example in Woman Walking. Joseph Csaky, after Archipenko, was the first sculptor in Paris to join the Cubists, with whom he exhibited from 1911 onwards. They were followed by Raymond Duchamp-Villon and then in 1914 by Jacques Lipchitz, Henri Laurens and Ossip Zadkine.
