Should scientists attend the ICUS?

• When the third International Conference on the Unity of Sciences (ICUS) was held in London in November 1974, scientists were made aware of the link between the International Cultural Foundation, the conference organisers, and Mr Sun Myung Moon, the head of the much criticised Unification Church (Nature 251, 661; 1974). Since then, scientists have been divided over whether to attend subsequent sessions of ICUS. Here, Professor N. Kurti of the Department of Engineering Science, Oxford University explains why he feels justified in attending them.
