Law and the Modern Mind first appeared in 1930 when, in the words of Judge Charles E. Clark, it fell like a bomb on the legal world. In the generations since, its influence has grown-today it is accepted as a classic of general jurisprudence.The work is a bold and persuasive attack on the delusion that the law is a bastion of predictable and logical action. Jerome Frank's controversial thesis is that the decisions made by judge and jury are determined to an enormous extent by powerful, concealed, and highly idiosyncratic psychological prejudices that these decision-makers bring to the courtroom.
