They may even successfully make the most fundamentally point most appropriately. It is a challenge for speakers to devote any proportion of their limited speaking time to acknowledgement and inclusion of perspectives of others. Absent dimensions must often be introduced with vigour. In doing so the possibility of weaving other perpectives into a larger pattern may have to be sacrificed. Such larger patterns may then be treated as of secondary importance, ignored, or regarded as unrealistic.
Participants then leave the meeting with little sense of a meaningful larger context.
These covert purposes may be of much greater importance than those which are overt. Collective efforts to articulate and honour a shared agenda may be privately viewed as exercises in tokenism. Participants may also bring their doubts to the encounter, or allow doubt concerning their own certainities to be triggered by the alternative perspectives of others. Speaking from certainity, a participant can only endeavour to persuade others and must remain deaf to the merits of their arguments. A measure of doubt enables a participants to learn and to benefit from the perspectives of others.
