Trust and justice are challenging humanity in scales and scopes unprecedentedly in the middle of globalization. Mankind is located at structural turning points and there are pressing needs to study justice and trust which glue mankind together. Trust and Justice: Complexity of Man, Complexity of Society, and Complexity Theory considers man as an organic complexity and society as an interactive complexity. Applying complexity theory, it discusses the implications and limitations of theories of justice. Wei-Bin Zhang analyses the dynamics of trust in modern societies. Nonlinear dynamic interactions between trust and deception and honesty and manipulations are emphasized. The author points out that some trustful relationships are not right if they are considered with broad perspectives. Modern rational civilization is bolstered by its ideology, an ideology that provides a structure for the creation, distribution, and consumption of wealth, power, and sex (and its associated products such as family and children). Zhang provides some insights into relationships between ideologies, trust, and justice. An interdisciplinary approach is applied to reveal the complexity of trust and justice.
