… (a) correct ideas and (b) camper vans come from?
Correct ideas, as everyone is undoubtedly aware, come from three kinds of social practice: the struggle for production, the class struggle and scientific experiment.
Camper vans (or RVs: song on this page requiring Flash) may come to WI harbours because they’ve studied the Safe Nights Ireland website, which (inter alia) lists all the public toilets in Ireland (many counties have none) and the WI facilities.
Incidentally, I have been told that WI now welcomes camper vans, having persuaded Bord Fáilte that the economy won’t collapse if it recognises the reality that the vans use the harbours. However, I haven’t seen that in writing anywhere; if anyone can point me towards a reliable source, please leave a Comment below.
