Gunnar Heinsohn

In collaboration with a famous colleague in Bremen, economist Otto Steiger, Heinsohn criticized the "barter paradigm" of money. Instead of money as a medium of exchange to facilitate barter, Heinssohn replaced it with a property based credit theory of money that stresses the indispensable role of secure property titles, contract law and especially contract enforcement, liability and collateral to create secure, transferable debt titles that central banks will accept as collateral for issuing bank notes.^[3][4][5][6]

Interest is being explained as a property premium instead.^[7] The paradigm provides institutional microfoundations for monetary theories of production developed in the Keynesian tradition. Credit theories of money have existed since mercantilism but have not become the dominating paradigm in monetary theory.^[8][9] Besides promoting their paradigm as an alternative foundation for triggering economic development (much in line with the insights of Hernando de Soto,^[10]Tom Bethell^[11] and Richard Pipes),^[12] Steiger has applied it to an analysis of the eurosystem.^{[13][14][15][16]}

While this approach has similarities with institutional economics, its major differences are (1) a non-universalist, cross-cultural approach that is in line with results from economic anthropology (Marshall Sahlins, Karl Polanyi, Marcel Mauss and others) and strongly doubts on the "homo oeconomicus" concept. It provides instead a specific explanation of various strategies of economic efficiency become functional only in monetary economies based on property and enforceable contracts;.^[17][18] Heinssohn proposes a reconstruction of the connection between property, enforceable contracts, interest, credit/money and the banking system and a possible explanation for technical progress and innovation. The difference in innovativity and progress between the monetary economics of antiquity and modern times is being explained as well.^[19][20] Heinsohn and Steiger's model has been discussed in some post-Keynesian circles,^[21][22] and it has been criticized by Nikolaus K.A. Läufer.^[23]

Heinssohn used demographic patterns to explain various historic events and tendencies. His work on genocide and antisemitism was strongly influenced by his demographic studies.

Heinsohn's contributions to genocide research include an encyclopedia of genocides,^[37] a generalized version of youth bulge theory^[38][39][40] and a new theory of Hitler's motivation for the Holocaust.^[41][42] Heinsohn suggested that Hitler wished to erase—physically, intellectually and spiritually—the meaning and heritage of Judaism and Jewish ethics from Germany and its European allies by literally destroying the Jews as a people. In so far Heinsohn explained the Holocaust:^[43] as an attempt by Hitler and his Nazi cohorts to wipe out the memory and the idea of Jewish ethics.^[44][45] He intended to enable Germans as a people to wipe out and conquer other people and lands without being hindered by conscience or ethical norms. Hitler assumed ethical normes were brought into Western civilization on the part of the Jews – and inherited by Christianity.

On the origin of sacrifice and priest kingship in Mesopotamia, Heinsohn suggested an explanatory model based upon a catastrophist view of ancient history and a psychoanalytic interpretation of sacrificial rituals.^[46][47] Heinsohn holds that the Jewish people were the first in occidental history to abolish sacrifice in the name of a general prohibition of killing, thereby providing an example to other religions still practicing sacrifice that this is unnecessary. As the Jewish prophet Hosea stated: "For kindness I desired, and not sacrifice, And a knowledge of God above burnt-offerings.".^[48] According to this view that is in some respects similar to a psychoanalytic view, antisemitic hatred has its origins in the feelings of guilt towards the sacrificed human or animal; turning those feelings of self-hatred towards those who do not take part in the ritual of sacrifice allows for continuing with the sacrificial practice.^[44] Heinsohn contrasts Jewish abstinence from sacrifice with the Christian belief in Jesus as someone who died for the Christians' sins, which he interprets as a regression to sacrificial practices of prehistory and as a core source of Christian-Jewish controversy.^[46]

Heinsohn proposed a revision of ancient chronology.^{[49][50][51][52]} Taking Immanuel Velikovsky's revised chronology as a starting point, Heinsohn went on to criticize Velikovsky's chronology as Biblical fundamentalism, proposing an even more drastic revision that is being disputed in circles of chronological revisionists.^[53]

His work on ancient chronology, focusing on his views on the stratigraphic record, resulted in some dramatic conclusions. Heinsohn opined that the currently accepted chronology was entrenched long before the scientific investigation of the past, based on the chronology provided in the Old Testament. He accused 19th century archaeologists of constructing their chronology around Bible synchronisms and of, more or less, following the chronology recorded by Eusebius in the fourth century, who made use of the histories of Egypt and Mesopotamia as well as the Old Testament. According to Heinsohn, bible synchronisms led to pharaohs Menes and Ramesses II being dated to the 4th millennium and the 14th century, respectively. As a result, Heinsohn concluded that they created a "phantom" history of two thousand years. In contrast, Heinsohn interpreted stratigraphic evidence to suggest that Egyptian and Mesopotamian civilizations arose around 1,200 BCE, not 3,200 BCE, as the textbooks say.

Heinsohn's ideas on ancient chronology were introduced to the English-speaking world in the Velikovskian journal Kronos in 1985.^[54] They have found support with a small number of writers and academics, most of whom are favorably disposed towards Velikovsky; amongst whom are Professor of Philosophy Lynn E. Rose, Professor of Classics at Bard College William Mullen, Professor of Art History Lewis M. Greenberg, speech writer and long-time observer of the Velikovsky scene Clark Whelton, German author Heribert Illig, and British writer Emmet Sweeney. However, his views have been severely criticized by several students of Velikovsky-inspired ancient chronology revision: Aeon editor Dwardu Cardona,^[55][56] New Zealand researcher Lester Mitcham,^[57] University of New Orleans Professor of History William H. Stiebing, Jr.,^[58] British researcher Anthony Rees^[59] and Aeon publisher Ev Cochrane.^[60]

In 2016, Heinsohn received the Liberty Award.^[61]
