Johnson, Alexander Bryan (1786-1867) American philosopher of language. Born in England, Johnson emigrated to America in 1801 and had a successful career as a banker. His philosophical interests centred upon language, whose misunderstanding he regarded as responsible for endless confusion and error. In a manner reminiscent of Berkeley he distinguished the ‘sensible’ meaning of terms, tied closely to the experiences to which they refer, from merely ‘verbal’ meaning. The sensible meaning of a sentence is given by what would now be thought of as the verification conditions or assertibility conditions of a sentence. Johnson's conviction that we erroneously attribute extra significance to sentences is a forerunner of the logical positivists’ polemic on the same point. Johnson's principal work was the Treatise on Language (1836). His remark that ‘we can no more exemplify with words that there is a limit to their applicability, than a painter can demonstrate with colours, that there are phenomena that colours cannot delineate’, is a striking anticipation of Wittgenstein's more famous distinction between what can be shown and what can be said.

Born in Gosport, Hampshire, England, at age 16 he emigrated to the United States, and settled at Utica, where he was a banker for many years. He was admitted to the bar, but never practised.
From his youth he had given all his leisure to the study of problems in intellectual philosophy, and especially of the relations between knowledge and language. He attempted to show the ultimate meaning of words, apart from their meaning as related to each other in ordinary definition, and thus to ascertain the nature of human knowledge as it exists independent of the words in which it is expressed.
His 1836 work, A Treatise on Language, was little recognised in his own time, and this remained the case for nearly a century after his death. It can now be seen to have anticipated the thrust of logical positivism, at least in arguing that misunderstandings of how language operates bedevil philosophical questions, and theories of modern linguistics.
He wrote several works on financial and political topics.
