Computing global structural balance in large-scale signed social networks

Structural balance theory affirms that signed social networks, i.e., graphs whose signed edges represent friendly/hostile interactions among individuals, tend to be organized so as to avoid conflictual situations, corresponding to cycles of negative parity. Using an algorithm for ground state calculation in large-scale Ising spin glasses, in this paper we compute the global level of …

Dynamics of Opinion Forming in Structurally Balanced Social Networks

In social network theory, a community of individuals characterized by friendly/hostile relationships is usually modeled as a signed graph having the individuals as nodes and their pairwise relationships as edges: an edge of positive weight expresses friendship, one of negative weight aversion or hostility [1,2]. According to Heider’s theory of structural balance [3], in a …

Continuous-Time Model of Structural Balance

It is not uncommon for certain social networks to divide into two opposing camps in response to stress. This happens, for example, in networks of political parties during winner-takes-all elections, in networks of companies competing to establish technical standards, and in networks of nations faced with mounting threats of war. A simple model for these …

John Dewey (1859 – 1952)

John Dewey was a leading proponent of the American school of thought known as pragmatism, a view that rejected the dualistic epistemology and metaphysics of modern philosophy in favor of a naturalistic approach that viewed knowledge as arising from an active adaptation of the human organism to its environment. On this view, inquiry should not be …

Richard Rorty (1931 – 2007) (Post 2)

Richard Rorty was an important American philosopher of the late twentieth and early twenty-first century who blended expertise in philosophy and comparative literature into a perspective called “The New Pragmatism” or “neopragmatism.” Rejecting the Platonist tradition at an early age, Rorty was initially attracted to analytic philosophy. As his views matured he came to believe …

Richard Rorty (1931 – 2007)

Richard Rorty (1931–2007) developed a distinctive and controversial brand of pragmatism that expressed itself along two main axes. One is negative – a critical diagnosis of what Rorty takes to be defining projects of modern philosophy. The other is positive – an attempt to show what intellectual culture might look like, once we free ourselves …

The Origin Story of a Slogan, “the Personal is Political”

One of the many slogans to come out of the culture war in the 1960s, ‘the personal is political’ best defines our own. The past six years of British and American politics have essentially been a fight about how valid and/or noble that sentiment is – how central a place personal feeling and identity should …

Baruch Spinoza

Spinoza’s account of religion has clear political ramifications. There had always been a quasi-political agenda behind his decision to write the TTP, since his attack was directed at political meddling by religious authorities. But he also took the opportunity to give a more detailed and thorough presentation of a general theory of the state that …

Saint Augustine

From ancient thought Augustine inherited the notion that philosophy is “love of wisdom” (Confessiones 3.8; De civitate dei 8.1), i.e., an attempt to pursue happiness—or, as late-antique thinkers, both pagan and Christian, liked to put it, salvation—by seeking insight into the true nature of things and living accordingly. This kind of philosophy he emphatically endorses, especially in his …

Ludwig Wittgenstein

Considered by some to be the greatest philosopher of the 20th century, Ludwig Wittgenstein played a central, if controversial, role in mid-20th-century analytic philosophy. He continues to influence, and incur debate in, current philosophical thought on topics as diverse as logic and language, perception and intention, ethics and religion, aesthetics and culture, and even political …
