"Out of Nothing"

According to common opinion, in the research of Jewish law and in the Halakhic literature, transactions in incorporeal estates are non-valid. However, economic life and the business world are based on these transactions. As a result, a gap was created between Halacha and reality. The book "Out of Nothing" proposes resolving this problem through Talmudic research methods, various issues which are discussed in the Talmudic law, including Davar She'lo Ba La'olam, Tovat Hanaha, and bills sale. In the course of the discussion it turns out that the Tannaitic ruling recognized these transactions, but Talmudic Halakha refused to recognize them. However, the Amoraim suggest various ways of mediation in order to enable transferring of future estate, debt bonds and so on.

The book proposes to take the bridges that the Amoraim proposed based on the Tannaitic law and to use them as tools for Halakhic validation of current market life.
