"Heinz von Foerster was the inventor of second-order cybernetics, which recognizes the investigator as part of the system he is investigating. The Beginning of Heaven and Earth Has No Name provides an accessible, nonmathematical, and comprehensive overview of von Foerster's cybernetic ideas and of the philosophy latent within them. It distills concepts scattered across the lifework of this scientific polymath and influential interdisciplinarian. At the same time, as a book-length interview, it does justice to von Foerster's élan as a speaker and improviser, his skill as a raconteur. Developed from a week-long conversation between the editors and von Foerster near the end of his life, this work playfully engages von Foerster in developing the difference his notion of second-order cybernetics makes for topics ranging from emergence, life, order, and thermodynamics to observation, recursion, cognition, perception, memory, and communication. The book gives an English-speaking audience a new ease of access to the rich thought and generous spirit of this remarkable and protean thinker"--

Historically, there has been great deliberation about the limits of human knowledge. Isaac Newton, recognizing his own shortcomings, once described himself as “a boy standing on the seashore . . . whilst the great ocean of truth lay all underscored before me.” In Ignorance, Nicholas Rescher presents a broad-ranging study that examines the manifestations, consequences, and occasional benefits of ignorance in areas of philosophy, scientific endeavor, and ordinary life. Citing philosophers, theologians, and scientists from Socrates to Steven Hawking, Rescher seeks to uncover the factors that hinder our cognition. Rescher categorizes ignorance as ontologically grounded (rooted in acts of nature-erasure, chaos, and chance-that prevent fact determination), or epistemically grounded (the inadequacy of our information-securing resources). He then defines the basis of ignorance: inaccessible data; statistical fogs; secreted information; past data that have left no trace; future discoveries; future contingencies; vagrant predicates; and superior intelligences. Such impediments set limits to inquiry and mean that while we can always extend our existing knowledge-variability here is infinite-there are things that we will never know. Cognitive finitude also hinders our ability to assimilate more than a certain number of facts. We may acquire additional information, but lack the facility to interpret it. More information does not always increase knowledge; it may point us further down the path toward an erroneous conclusion. In light of these deficiencies, Rescher looks to the role of computers in solving problems and expanding our knowledge base, but finds limits to their reasoning capacity. As Rescher's comprehensive study concludes, ignorance itself is a fertile topic for knowledge, and recognizing the boundaries of our comprehension is where wisdom begins.
