Inamdar, the Organizing Secretary of Foundation Lectures, Registrar (Evaluation), Members of Faculty, Syndicate and AC, media personnel, invitees, ladies and gentlemen, good morning and Greetings of teacher’s day to you all. As an alumnus of this university, I feel greatly honored to be here in the company of my former colleagues and fellow teachers and also meet the new faculty members. As a customary requirement let us remind ourselves of Sir S. Radhakrishnan the illustrious former President of India in whose honor we celebrate, his birthday as ‘Teacher’s Day’. He was a world teacher and enjoyed great respect. There is so much to talk about Radhakrishnan, his contributions to philosophy, his views on life, his services as diplomat, and relation with the Russian monarch Stalin as well as anecdotes associated with him. I am equally happy to be part of the ‘Foundation Day’ celebration observed in recognition of the contributions of the early architect of this university i.e. Dr. D. C. Pavate and deliver Pavate Memorial lecture. He was VC of this university for about 13 years. I took my admission for my Masters Degree in the year 1967 while he was the VC. He was a very strict disciplinarian, and could take hard decisions. He brought eminent faculty members from different parts of the country and that is how good foundation was laid for academic progress of this university. The majestic and very imposing ‘Vidya-Soudha’ is his contribution to the university. Furthermore, he was the guiding force for me during my term as VC. Therefore, being here today is a double bonanza for me: celebration of University’s Foundation Day & Teacher’s day together. Thank you for this wonderful opportunity. In this talk I wish to focus on the fast changing education scenario and consequent compulsions on the teachers to remain relevant. In this context, let us first have a bird’s eye view to see how our education system (E 1.0-4.0) evolved, how industrial revolutions (IR 1.0- 4.0) took place and the relationship between the two. Finally, we should ask what the way forward is and what factors would guide the future education? Karnatak University Journal of Science Page 2 September 2020 Vol.51 S. K. Saidapur Significance of Education: First let us ask what education is all about. What is the difference between education and literacy? The latter provides ability to read and write. But, mere literacy and ability to read and write is not education. Education is the manifestation of ‘perfection’ said Vivekananda. If we accomplish perfection then all conflicts within and between us will at once vanish. A well educated person will not inflict pain on others unduly. Education is for production of human resource; competent people are needed in all facets of human endeavors and to sustain peaceful co-existence of human societies and the nations. It was Jawaharlal Nehru who said in his convocation address of Allahabad University and I quote “A University stands for humanism for tolerance, for reason, for the adventure of ideas and for the search of truth. It stands for onward march of the human race towards even higher objectives. If the universities discharge their duties adequately, then it is well with the Nation and the people”. By implication, all ills of the society can be attributed to declining quality of varsity education.
