Beginnings of Science
The oldest known treatise on surgery..... written in Egypt 5,000 years ago, discloses the thoughts of the earliest man who reveals a scientific attitude of mind.
This treatise is therefore the earliest document in the history of science. A history of science might be based on some more or less logical system of definitions and classification. Such systems and such points of view belong to relatively recent and mature periods.
The periods at which primitive man of different races began to have conscious appreciation of the phenomenon of nature, of number magnitude and geometric forms can never be known, nor the time at which their elementary notions began to be so classified and associated as to deserve the name of science.
Very early in any civilization, however there must obviously have been developed simple processes of counting and adding, of time and distance measurement, of the geometry and arithmetic involved in land measurement and in architectural design and construction.
