(2) Mz Cope examines Plato’s arguments against Protagoras 
which are mainly these: 
(a) Protagoras asserts that the views, opinions, beliefs of 
everyone are true to himself as he conceives them; but the 
majority of mankind think Protagoras’ theory wrong; therefore 
this opinion is true to them and yet is contradictory to the theory; 
therefore the theory is in conflict with itself and so is false. 
(8) Even if there were no other than the subjective standard of 
present truth and present right, there must be of future ; for in 
that all men’s opinions and thoughts are not equally true and 
valid. The man of science can, in certain cases, predict what 
will happen in future time—the idudrns cannot; his fancies 
and impressions are here of no value; and are liable to be false 
even to himself. 
Mr Cope developes these arguments and shews why he con- 
siders them to be satisfactory. 
_ The paper concludes with a defence of Plato against a charge 
of self-contradiction in the statements and views of the Theetetus 
and Sophist on the subject of ‘false opinion.’ 
The Master oF TRINITY made a few remarks; in the course 
of which he stated that, in his opinion, the ideas of Protagoras 
took a somewhat wider range than the senses alone; and that 
Plato was not primarily attacking Protagoras in the Theetetus, 
but some contemporary Sophist.
