In this paper there is an attempt to discuss the relationship between Science, Science and common sense. All are knowledge-seeking but their enquiries in all cases are not same. The objectivity in Science through factual evidence is of paramount importance. Scientific knowledge is reliable and objectively proved. Science is understood through its nature, method and justification. Social Science may be treated as socio-cultural aspect of human behavior. The knowledge derived from Social Sciences through research and investigation is mainly towards the development and progress of socio-individual relationship with moral value having human significance. Its method is also analytical and persuasive through scientific analysis in terms of factual scrutiny and objective discovery. But, both Science and Social Science are concerned with worldly affairs and the pursuit of knowledge is advanced in both keeping in tune with their respective aims and programmes. Both Science and Social Science attempt (in their way) to avoid mysticism, dogmatism and different types of prejudices.
