The author has done an excellent work by assembling a vast amount of information on a general topic such as "Traditional knowledge" that was acquired by the primitive people through trial and errors over thousands of years. The pamphlet has been forwarded by Mr. Vinay Lal. He sketches a bird-eye view on traditional knowledge to catch glimpses of colonial era, past glory of developed nations and significance of indigenous knowledge of third world countries by citing number of examples from global history. Further, he also emphasised the role played by pamphlets in several mass awakening revolutions in world history viz. class struggles in France, propagation of Marxist philosophy and so on and so forth. The next section deals with how the traditional knowledge systems are mother of all sciences and their potential role in socio-economic development. The booklet has included some interesting examples from UNESCO’s project named “Knowledge of Nature”.

Overall, the booklet has successfully conveyed the message about the importance of conservation of traditional knowledge and its potential role for socio-economic upliftment of rural people.
