tributed various miraculous actions, but these are probably 

 explicable in tenns of his strong psychological personality, 

 (a similar strength of personality was possessed by 

 Gautama Buddha). Particularly interesting are the records 

 by Christ's immediate followers of his apparent physical 

 reappearance after death: if these are correct, then it would 

 seem that this phenomenon might indicate a new, but very 

 rare, property of man. However it appears to be better 

 at present to explain this event in terms of a purely psycho- 

 logical projection taking place in the minds of those re- 

 porting it. Nevertheless these people were convinced of 

 the reality of human resurrection, and they actively ad- 

 vanced Christianity in the Roman Empire, succeeding in 

 acquiring the recognition of the Emperor. Unfortunately 

 the absolute acceptance of this religion by the majority of 

 the European intellectuals for centuries afterwards made 

 it impossible to undertake any open-minded enquiries into 

 Nature, the Church adopting the view that essentially all 

 had been solved by the Greeks. Consequently European 

 civilization underwent a Dark Age (the Medieval period 

 from c. 500 A.D. to c. 1300 A.D.), when earlier acquired 

 knowledge was merely handed on to succeeding genera- 

 tions. However a few men, notably Francis Bacon (c. 

 1620), saw the necessity of testing scientific theories by 

 actual experiment, and that an advance in real knowledge 

 of Nature would make possible a better control over na- 

 tural forces by Man to meet his own needs. It was not until 

 Bacon's suggestions were made, however, that men 

 attempted to carry out appreciable experimental work. 



The next great civilization to appear after the time of 

 Christ was that of the Arabs. These people were inspired 

 by the great religious teacher Muhammed (c. 640 A.D.) 

 who declared the existence of a single God, and that he
