Abstract
The concept of science has undergone continuous evolution from ancient philosophical inquiry to contemporary experimental and verification-based frameworks. In ancient times, science was primarily viewed as knowledge of causes, deeply embedded in philosophy. During the medieval period, observation and experience began to supplement pure reasoning. The modern scientific revolution emphasized experimentation, mathematical formulation, and universal laws. Twentieth-century philosophy of science introduced falsifiability, relativity, and provisional truth.
This paper presents a certified comparative analysis of these stages and culminates in a contemporary integrative definition proposed by Dr. Prof. Awadhesh Kumar Shailaj, which conceptualizes science as an art of logical thinking and controlled experimentation grounded in research-based verification. The study demonstrates that science is not static knowledge but a dynamic, evolving epistemological process.
Keywords: Science, Definition of Science, Philosophy of Science, Scientific Method, Comparative Study, Epistemology
1. Introduction
Science has never been a fixed concept. Its meaning and methodology have evolved alongside human intellectual development. From metaphysical reasoning to empirical experimentation, the definition of science reflects shifts in how humans understand truth, reality, and knowledge. This paper aims to systematically trace this evolution and establish a comprehensive contemporary definition suitable for multidisciplinary application.
2. Science in Ancient Thought
In ancient philosophy, science was inseparable from metaphysics and logic. Knowledge was primarily deductive, focusing on causal explanations of natural phenomena. Empirical testing was secondary to rational coherence.
Certified Interpretation:
Science was regarded as philosophical knowledge aimed at understanding causes rather than experimentally verifiable laws.
3. Medieval Transition: Observation and Experience
The medieval period introduced observation and experiential validation into scientific inquiry. Although still influenced by theology, this phase marked a shift toward empirical awareness.
Certified Interpretation:
Science became a bridge between rational thought and experiential observation.
4. Modern Scientific Revolution
The modern era established experimentation, measurement, and mathematical representation as the foundation of science. Universal laws replaced speculative explanations.
Certified Interpretation:
Science was defined as a systematic enterprise discovering natural laws through controlled experimentation.
5. Twentieth-Century Philosophy of Science
Twentieth-century thinkers emphasized falsifiability, relativity, and provisional truth. Absolute certainty was replaced by testable and revisable knowledge claims.
Certified Interpretation:
Science became a self-correcting process rather than a repository of final truths.
6. Contemporary Integrative Definition of Science
Proposed Definition (Certified):
English:
Science is an art of logical thinking and experimentation on any stimulus situation in controlled physical conditions and has faith in research-based verification of any hypothetical or subject-oriented circumstances.
Hindi:
विज्ञान नियंत्रित भौतिक परिस्थितियों में किसी भी उत्तेजक स्थिति पर तार्किक चिंतन और प्रयोग की एक कला है तथा किसी भी काल्पनिक या विषय-उन्मुख परिस्थितियों के शोधपरक सत्यापन में विश्वास करता है।
This definition integrates logic, experimentation, hypothesis testing, and verification, making it applicable across natural, social, psychological, and interdisciplinary sciences.
7. Discussion
The certified comparative analysis reveals that science has progressed from speculative reasoning to methodological rigor. The contemporary definition synthesizes philosophical depth with empirical discipline, fulfilling both classical and modern scientific criteria.
8. Conclusion (Certified Statement)
This study certifies that the definition proposed by Dr. Prof. Awadhesh Kumar Shailaj represents a comprehensive, contemporary, and globally relevant understanding of science. It successfully bridges ancient philosophical insight with modern experimental methodology, positioning science as an evolving epistemological process rather than static knowledge.
