There seems not to exist a word――for words are old while meanings may be new――which answers exactly to what I shall speak of as _Intelligence_. But space being short for what has to be said, I will not waste any in preliminary definitions. That which I mean by Intelligence will become evident by what I expect from its presence and attribute to its absence. I start from the assumption that it already exists, however insufficiently; and I deduce from what it has done that its nature is to intensify and extend. Whether this will be witnessed in the near future, or whether it may be checked by adverse circumstances, is no concern of mine. Writers of this series, and several others besides, have enlarged on the political and economic contingencies to which Intelligence, or persons presumed to have it, seem likely to be exposed. Whether Intelligence may become the weapon of a dominant caste, as was the hope of Comte, of Renan, and, at one moment, of Mr. H. G. Wells; or whether, as proposed by M. Charles Maurras, Intelligence shall be honoured with a subordinate function in some sort of Fascist State, I am inadequate to judge. Nor do I even feel certain that history has shown, or economic theory demonstrated, that Intelligence can be bullied or starved out of existence. Meanwhile let me confess that what I have to say about the Future of Intelligence is the expression as much of my hopes as of my convictions, both, however, arising from a longish experience of changes already brought about, and changes beginning to be brought about, by the particular, and perhaps rather modern, something I mean by _Intelligence_. What _I_ mean, and what, under restriction to that meaning, appears _to me_ likely or desirable. By underlining these personal pronouns, I am able to forestall the mention of one great change which Intelligence is already initiating, namely, the recognition and avowal that what one thinks (as distinguished from what primers, manuals and other authorities have taught one to believe) is――well, _just what one does think_, and neither the consensus of human opinion nor the revelation of the Deity’s irrefragable truth.
