These aims are also reflected in Roman-Dutch law. The "consortium omnis vitae" refers to all the duties which fall under the relationship of married spouses. Death dissolves a marriage, but the law provides also for dissolution by the high court on some ground which renders the marriage voidable, or following upon an order presuming the death of the one spouse, or on some ground arising after marriage which is recognised as a ground for divorce. Marriage has its foundations in a variety of bailiwicks beyond the legal realm, including philosophy, religion, culture and social practice. In "Rattigan v Chief Immigration Officer, Zimbabwe", Gubbay CJ described marriage as  a juristic act "sui generis". It gives rise to a physical, moral and spiritual community of life - a "consortium omnis vitae". It obliges the husband and wife to live together for life (more realistically, for as long as the marriage endures) and to confer sexual privileges exclusively upon each other [...]. The duties of cohabitation, loyalty, fidelity and mutual assistance and support flow from the marital relationship. To live together as spouses in community of life, to afford each other marital privileges and to be ever faithful, are the inherent commands which lie at the very heart of marriage. Although a Zimbabwean case, "Rattigan" is widely cited in South African jurisprudence; it continues:  Marriages are almost invariably entered into by parties who have deep affection for one another and who intend to devote the remainder of their lives together. Although the condition of matrimony does not, as a concept of law, make the spouses one flesh—una caro—it nonetheless embodies the obligations to found a home, to cohabit, to have children and to live together as a family unit. It is the most fundamental institution known to mankind—"the first step from barbarism" and "the true basis of human progress". Gubbay also cited in "Rattigan" the words of Justice Field in "Maynard v Hill", which characterised marriage as  an institution, in the maintenance of which in its purity the public is deeply interested, for it is the foundation of the family and of society, without which there would be neither civilisation nor progress [...]. It is [...] a social relation, like that of parent and child, the obligations of which arise not from the consent of concurring minds, but are the creation of the law itself, a relation the most important, as affecting the happiness of individuals, the first step from barbarism to incipient civilisation, the purest tie of social life, and the true basis of human progress.
