status of the "international dateline" was the subject of considerable debate, he published his best known work, "Agan HaSahar". He is said to have considered that precious few could understand his work, and printed a very limited edition of only several hundred copies. The book today commands a rich premium from collectors, on the rare occasions when a copy becomes available for sale. His most famous disputant was Rav Menachem Kasher, whom he attacked vigorously in "Agan HaSahar", following Kasher's cavalier dismissal of his published opinions on the dateline controversy. In his book ''Torah and Existence'', he cogently argues that the purpose of the world revolves around Torah. The first chapter contains an elaboration of his opinion that the founding of the modern State of Israel constituted the "Atchalta d'Geula" (Beginning of the Redemption), though he strongly opposed much of the policies and leadership of the state.
