useful and congenial co-operation as a more fundamental difference.

In the case of a body of intellectual workers one might at first sight
suppose that so small a distinction as that of belonging to a
different nationality--sex, of course, is an infinitely profounder
difference--would not be a bar to unrestricted intellectual
co-operation.

But in point of fact it is in every country, in every learned society,
a uniform rule that when foreign scientists or scholars are admitted
they are placed not on the ordinary list of working members, but on a
special list.

One discerns that there is justification for this in the fact that a
foreigner would in certain eventualities be an incompatible person.

One may think of the eventuality of the learned society deciding to
recognise a national service, or to take part in a national movement.
And one is not sure that a foreigner might not be an incompatible
person in the eventuality of a scientist or scholar belonging to a
nationality with which the foreigner's country was at feud being
brought forward for election. And he would, of course, be an
impossible person in a society if he were, in a spirit of chauvinism,
to press for a larger representation of his own fellow-countrymen.

Now this is precisely the kind of way man feels about woman. He
recognises that she is by virtue of her sex for certain purposes an
incompatible person; and that, quite apart from this, her secondary
sexual characters might in certain eventualities make her an
impossible person.
