Dear Mr. Tapan,
Well, mustering the knowledge (by himself) in any field is definitely not a redundancy and such knowledge is greatly appreciated when used appropriately on the issues of life from one corner to other, for the benefit of an individual or Society. Merely forcing the mind into a system, a pattern, obviously doesn't necessarily fetch any knowledge! Addition of interdisciplinary subjects to law, make the students leaving no choice but have got to learn them! Please let me know if I have interpreted your first thread wrongly and how!
How is it a right direction?
After all, the major brain drain is happening from IITians only, so what is the advantage of introducing law subjects to them! So far, IITKGP is planning to introduce law subject(s) and why don't all the IIT schools implement the same? Is it not a brand building exercise for the IITs? Preponderance of IITians are settled in the USA or making huge money in the US, have contributed very little to these Govt. supported prestigious colleges! I don't feel it's a good move unless you have a legitimate reason here! I would say, instead spend the same money for the betterment of Govt. Law colleges to churn out the best lawyers (for India).
Why only Biology and why not other Sciences including management or leadership skills etc., are sine a qua non for lawyers?
I woud say, introducing joint degree programs would give an option for students to choose on what they want to pursue!
Please consider these are only my views, there may be any substantial information which is beyond my imagination!
