That is why we maintain there is a need for the formation of small groups based on the concept of affinity, even tiny groups made up of very few comrades who know each other and deepen this knowledge because there cannot be affinity if one does not have knowledge of the other. One can only recognise one’s affinities by going into the elements that determine one’s differences, by frequenting each other. This knowledge is a personal fact, but it is also a question of ideas, debate, discussions. A small group of comrades, a small group who simply meet in the evening to have a chat would not be an affinity group but a group of friends, pub-mates who meet in the evenings to talk about anything under the sun. On the contrary, a group that meets to discuss things and in discussing prepares itself for doing and through that doing contributes to developing discussion that transforms itself into discussion about things to be done, this is the mechanism of the affinity group. So how then can affinity groups enter into contact with others where the deepened knowledge that exists in the single group does not necessarily exist? This contact can be assured by informal organisation.
