ABSTRACT
"What has concluded that we should conclude about it"! This now famous remark of William James is a warning to all writers on philosophical topics, and it is certainly applicable when the theme has been possibility. Nevertheless, I am tempted to conclude, at least, in the manner of one going home after an evening's conversation, romantically and unrestrained by the doubts and objections of opponents in the argument. Also, I have another excuse. Possibility has a romantic sound about it, and readers, if there are any at this point, will be disappointed if some definite possibility is not pointed out. I have such a possibility in mind, and although I shall have to deflate it at the end, it may prove amusing and possibly illuminating while it is being flown in the sky of speculation.
