Hassan Ansari

When Sabine Schmidtke and Hassan Ansari, an Iranian national, met more than a decade ago in Tehran, Ansari was a ­student of the traditional religious system in Qum and Tehran (the “Hawza”). Ansari had read Schmidtke’s doctoral thesis The Theology of al-ʿAllāma al-Ḥillī (d. 726/1325), which was translated into Persian and published in Iran in 1999. Schmidtke’s scholarship changed Ansari’s approach to Islamic sources and was one of the reasons why he became ­interested in historical studies on Islamic theology. “The historical approach is not only useful, it is necessary,” says Ansari. “I talk now as a Muslim scholar. We need to have this kind of historical studies to change our approach to our own intellectual and legal tradition and its holy texts.”

What makes Ansari a particularly exceptional scholar is his combination of Western and traditionalist Islamic training. In the “Hawza” in Qum and Tehran, he successfully completed the very highest level of study for the rank of Ayatollah, in the Shi‘i ­clerical system. He also has studied Islamic and Western philosophy and Islamic intellectual history at universities in Tehran, Beirut, and Paris. “Hassan’s command of the sources is extremely wide-­ranging,” says Schmidtke, “and he combines this with the very best ­historical-critical approach to the subjects and texts he is dealing with. He is an intimate connoisseur of manuscripts, Arabic and Persian, and the spectrum he covers is immense.”

Will It Become Decisive Enough?

What do the humanities have to do with the environment? As they are commonly understood, environmental problems are issues that manifest themselves primarily in the environment itself. Natural scientists research these problems and suggest solutions, aided by technology, economics, and policy. It was scientists who defined the modern usage of the concept of “the environment” after World War II. Ecologist William Vogt famously used it in his 1948 volume The Road to Survival: “We live in one world in an ecological—an environmental—sense.” He and others at the time thought of “the environment” as a composite of issues that had been in the making for some time—most prominently, population growth, which had been much discussed since the World Population Conference in Geneva in 1927, but also soil erosion, desertification (observed by Paul Sears in his famous 1935 book Deserts on the March), pollution, food, poverty, and starvation.

Are Humans a Major and Defining Force on the Geological Scale?

The word “Anthropocene” has had a formidable career in the last few years and is often heard among global change scientists and scholars, in policy circles, green popular movements, and think tanks, and in all spheres where environmental and climate issues are discussed. In the literal, and limited, sense it is a geological concept, on a par with other periods or epochs during the Cenozoic era, such as the Holocene (“Recent Whole,” the period since the last glaciation, ca. eleven thousand years ago). The word anthropos (Greek for “human”) in it indicates that humans, as a collectivity across time, serve as a major and defining force on the geological scale.

Whether this is so is a matter of definition, and it is an ongoing and open issue whether this is the case. The Royal Geological Society of London handles these kinds of issues through its Stratigraphy Commission, which expects to be able to present its view on the matter to the Society by 2016. The chief criterion in their search for evidence is whether there will be enough lasting and significant traits left of the “strata” of the Anthropocene to merit it an individual geological period, or epoch (Zalasiewic et al. 2011). This is less a philosophical or judgmental than an empirical issue. Are the assembled impacts and remnants of human activities in the lithosphere, biosphere, atmosphere, pedosphere (the layer of soils), and cryosphere (the layer of ice) so overwhelming that we can be certain that the “deep future” will still be able to register the strata of humanity embedded into Earth itself?


Doubts Arise Over Claims of Evidence for Cosmic Inflation

In September, Planck researchers confirmed Member Raphael Flauger’s assertion that the level of galaxy dust in this Planck slide was underestimated by the BICEP team.

“Space Ripples Reveal Big Bang’s Smoking Gun,” read the New York Times headline last March 17. In a seemingly momentous news conference at the Harvard–Smithsonian Center for Astrophysics, researchers using a BICEP (Background Imaging of Cosmic Extragalactic Polarization) telescope at the South Pole announced that they had detected the first direct evidence for cosmic inflation, a theory about the very beginnings of the universe first proposed in 1979. 

The BICEP announcement claimed that the first images of gravitational waves, or ripples in spacetime, had been detected, a tantalizing and long hoped-for connection between quantum mechanics and general relativity. The landmark claim ignited the field and led to talk of a new era of cosmology.

At the Institute for Advanced Study, Raphael Flauger, Member (2013–14) in the School of Natural Sciences, began looking closely at the data. The year prior, Flauger had analyzed the first round of cosmic microwave background data released by the Planck satellite, a mission of the European Space Agency, which the BICEP team had used in its findings. 


Of Historical Note

The following excerpt is from the article “Can We Survive Technology?” by John von Neumann, published by Fortune magazine in 1955. Von Neumann was among the Institute’s first Professors and its youngest. Having pioneered the modern computer, game theory, nuclear deterrence, and more, von Neumann illuminated the fields of pure and applied mathematics, computer science, physics, and economics. He remained a Professor at IAS until his death in 1957.

"All experience shows that even smaller technological changes than those now in the cards profoundly transform political and social relationships. Experience also shows that these transformations are not a priori predictable and that most contemporary 'first guesses' concerning them are wrong. For all these reasons, one should take neither present difficulties nor presently proposed reforms too seriously.

"The one solid fact is that the difficulties are due to an evolution that, while useful and constructive, is also dangerous. Can we produce the required adjustments with the necessary speed? The most hopeful answer is that the human species has been subjected to similar tests before and seems to have a congenital ability to come through, after varying amounts of trouble. To ask in advance for a complete recipe would be unreasonable. We can specify only the human qualities required: patience, flexibility, intelligence."
