<P> When it came to biography, Johnson disagreed with Plutarch's use of biography to praise and to teach morality . Instead, Johnson believed in portraying the biographical subjects accurately and including any negative aspects of their lives . Because his insistence on accuracy in biography was little short of revolutionary, Johnson had to struggle against a society that was unwilling to accept biographical details that could be viewed as tarnishing a reputation; this became the subject of Rambler 60 . Furthermore, Johnson believed that biography should not be limited to the most famous and that the lives of lesser individuals, too, were significant; thus in his Lives of the Poets he chose both great and lesser poets . In all his biographies he insisted on including what others would have considered trivial details to fully describe the lives of his subjects . Johnson considered the genre of autobiography and diaries, including his own, as one having the most significance; in Idler 84 he explains how a writer of an autobiography would be the least likely to distort his own life . </P> <P> Johnson's thoughts on biography and on poetry coalesced in his understanding of what would make a good critic . His works were dominated with his intent to use them for literary criticism . This was especially true of his Dictionary of which he wrote: "I lately published a Dictionary like those compiled by the academies of Italy and France, for the use of such as aspire to exactness of criticism, or elegance of style". Although a smaller edition of his Dictionary became the standard household dictionary, Johnson's original Dictionary was an academic tool that examined how words were used, especially in literary works . To achieve this purpose, Johnson included quotations from Bacon, Hooker, Milton, Shakespeare, Spenser, and many others from what he considered to be the most important literary fields: natural science, philosophy, poetry, and theology . These quotations and usages were all compared and carefully studied in the Dictionary so that a reader could understand what words in literary works meant in context . </P> <P> Johnson did not attempt to create schools of theories to analyse the aesthetics of literature . Instead, he used his criticism for the practical purpose of helping others to better read and understand literature . When it came to Shakespeare's plays, Johnson emphasised the role of the reader in understanding language: "If Shakespeare has difficulties above other writers, it is to be imputed to the nature of his work, which required the use of common colloquial language, and consequently admitted many phrases allusive, elliptical, and proverbial, such as we speak and hear every hour without observing them". </P> <P> His works on Shakespeare were devoted not merely to Shakespeare, but to understanding literature as a whole; in his Preface to Shakespeare, Johnson rejects the previous dogma of the classical unities and argues that drama should be faithful to life . However, Johnson did not only defend Shakespeare; he discussed Shakespeare's faults, including his lack of morality, his vulgarity, his carelessness in crafting plots, and his occasional inattentiveness when choosing words or word order . As well as direct literary criticism, Johnson emphasised the need to establish a text that accurately reflects what an author wrote . Shakespeare's plays, in particular, had multiple editions, each of which contained errors caused by the printing process . This problem was compounded by careless editors who deemed difficult words incorrect, and changed them in later editions . Johnson believed that an editor should not alter the text in such a way . </P>
