Few recent advances in science have generated as much excitement and controversy as human embryonic stem cells. The potential of these cells to replace diseased or damaged cells in virtually every tissue of the body heralds the advent of an extraordinary new field of medicine. Controversy arises, however, because current techniques required to harvest stem cells involve the destruction of the human blastocyst. This even-handed, lucidly written volume is an essential tool for understanding the complex issues - scientific, religious, ethical, and political - that currently fuel public debate about stem cell research. One of the few books to provide a comprehensive overview for a wide audience, the volume brings together leading scientists, ethicists, political scientists, and doctors to explain this new scientific development and explore its ramifications.

Lev Vygotsky has acquired the status of one of the grand masters in psychology. Following the English translation and publication of his Collected Works there has been a new wave of interest in Vygotsky, accompanied by a burgeoning of secondary literature. Ronald Miller argues that Vygotsky is increasingly being 'read' and understood through secondary sources and that scholars have claimed Vygotsky as the foundational figure for their own theories, eliminating his most distinctive contributions and distorting his theories. Miller peels away the accumulated layers of commentary to provide a clearer understanding of how Vygotsky built and developed his arguments. In an in-depth analysis of the last three chapters of Vygotsky's book Thinking and Speech, Miller provides a critical interpretation of the core theoretical concepts that constitute Vygotsky's cultural-historical theory, including the development of concepts, mediation, the zone of proximal development, conscious awareness, inner speech, word meaning and consciousness.
