Ambedkar was born in a caste that was classified as untouchable, became a leader of human rights in India, a prolific writer, and a key person in drafting modern India's constitution in the 1940s. He wrote extensively on discrimination, trauma and what he saw as the tragic effects of the caste system in India.
Ambedkar described the Untouchables as belonging to the same religion and culture, yet shunned and ostracised by the community they lived in. The Untouchables, observed Ambedkar, recognised the sacred as well as the secular laws of India, but they derived no benefit from this. They lived on the outskirts of a village.
Segregated from the rest, bound down to a code of behaviour, they lived a life appropriate to a servile state. According to this code, an Untouchable could not do anything that raised him or her above his or her appointed station in life. The caste system stamped an individual as untouchable from birth.
Thereafter, observed Ambedkar, his social status was fixed, and his economic condition was permanently set. The tragic part was that the Mohmedans, Parsis and Christians shunned and avoided the Untouchables, as well as the Hindus.
Ambedkar acknowledged that the caste system wasn't universally absolute in his time; it was true, he wrote, that some Untouchables had risen in Indian society above their usually low status, but the majority had limited mobility, or none, during Britain's colonial rule.
According to Ambedkar, the caste system was irrational. Ambedkar listed these evils of the caste system: it isolated people, infused a sense of inferiority into lower-caste individuals, and divided humanity.
The caste system was not merely a social problem, he argued: it traumatised India's people, its economy, and the discourse between its people, preventing India from developing and sharing knowledge, and wrecking its ability to create and enjoy the fruits of freedom.
The philosophy supporting the social stratification system in India had discouraged critical thinking and cooperative effort, encouraging instead treatises that were full of absurd conceits, quaint fancies, and chaotic speculations.
The lack of social mobility, notes Ambedkar, had prevented India from developing technology which can aid man in his effort to make a bare living, and a life better than that of the brute.

Ambedkar stated that the resultant absence of scientific and technical progress, combined with all the transcendentalism and submission to one's fate, perpetrated famines, desolated the land, and degraded the consciousness from respecting the civic rights of every fellow human being.
According to Ambedkar, castes divided people, only to disintegrate and cause myriad divisions which isolated people and caused confusion. Even the upper caste, the Brahmin, divided itself and disintegrated. The curse of caste, according to him, split the Brahmin priest class into well over 1400 sub-castes. This is supported by census data collected by colonial ethnographers in British India,now South Asia .
