The Book consists of two interrelated theses. one reflexive modernization and other issue of risk. The concept of risk is directly bound to the concept of reflexive modernization.It shows how classical modernization is different from reflexive modernization. Risk may be defined as a systematic way of dealing with hazards and insecurities induced and introduced by modernization itself.The risk and hazards of today is of global nature of their threat to people,animals and plants .It results in global industrial pollution,contamination of air,water,foodstuffs etc. and also sickness ,death of plants, animals and people. Another dimension of risk is social transformation with modernity.There is a process of individualization deprive class distints but inequalities by no means disappear.There is a shift from the system of standardised full employment to the system of flexible and pluralised under employment.Risk of scientific development increases disproportionately faster than solution. With the globalisation of industrial society political system looses its function as modernization, technoeconomic system changes the realms of social life and on other hand political systens pre-supposes condition of the system.
