Intensive, detailed, exhaustive

Arthur Jensen's bibliography is characterized as breathtaking and his scien tific work as intensive, detailed, exhaustive, fair-minded, temperate, and courageous. Specific articles and books are targeted as must reading. I arg ue that Jensen's characterization of the influence of the Berkeley psycholo gy department in the 1940's reflects his own intellectual biases rather tha n those of the department. Jensen's work is praised as an extension of the British Biological-Theoretical Tradition which attempts to integrate psycho logical, biological, social genetic, sociological, and cultural processesl in a coherent theoretical framework. A new definition of Jensenism, based o n the Jansenist heresy, is provided.
