Nowadays, many educated persons immersed in Vedic and Sastric knowledge, and classic scholarship have lost faith in the texts of which they are masters; they have become afraid to stick firmly to Dharma, for it is being laughed at by their cynical friends; they have yielded to the crooked arguments of critics and sold their heritage for trivial returns; they interpret the Ekadasi fast as one of the means for regulating health, the waving of the camphor flame as a remedy for asthmatics, pranayama as helping digestion, pilgrimages as educational tours, charity as a means of self-advertisement... thus demeaning and desecrating the holy injunctions of Dharma.

Such men only deceive the world; they are barbarians who do not know or heed the principles of Dharma. They can learn something from a perusal of Manudharma.

Aarsham dharmopadesam cha
Vedasastra a-virodhinaa
Yastharkenaanusandhaththe
Sa dharmam veda, netharah

Thus said Manu: "Any person who wants to know Dharma can know it only by following a system of Logic or Tarka that is not opposed to Veda and Sastra". No conclusion opposed to Veda can be logical. Dry logic is profitless and Manu does not recommend it to those who want to study the Vedas, etc. Still there are many today who stick to this logical reasoning and following Adharma themselves, drag others too with them into the wrong path. That is why Vedavyasa declared long ago:

Na yakshyanthi, na hoshyanthi, hethuvadavimohithaah
Nimmokshyaham karishyanthi, hethuvaadavimohithaah

That is to say, those who follow the path of Causalism and logic, seeking cause-and-effect connection, will not offer sacrifices in the sacred fire, they will involve themselves in low demeaning acts. Vedavyasa has said this in Aranyaparva of Mahabharatha, while describing the conditions that are to be expected in the Kali era.
