• About Ram Manohar Lohiya:
  • He was a staunch supporter of positive discrimination a state shall make to uplift the position of women, OBCs, and other vulnerable groups. This makes sense in a present-day society where reservation is being provided to the various group by the supreme law of the land under Art 16(b) (reservation to OBC, SC & ST) and by 73rd and 74th C.A.A (women in local bodies elections.).

  • He called for the eradication of caste and class-based society. At present, it is required to establish an egalitarian and inclusive society. 
  • He called for planned production. To achieve the goals of SDG, and fight the twin menace of climate change and global warming, his idea needs to be implemented with true intentions. 
  • He was critical of foreign domination, which is needed to maintain the sovereignty of the nation and so that its developmental benefits reach the last man of the society. 
  • He was critical of arms and weapons and advocated for Satyagraha to put one's unheard voice. This is essential to achieve peace and harmony in the world. Even international organizations are striving for disarmament in present times. 
  • He also advocated politics as a practice of ethics and values, which is desirable in the present political environment.
