Upon the introduction of Act 1 Scene 5, Lady Macbeth is brought into the plot of the play. In this soliloquy, Lady Macbeth comments on her thoughts after having read a letter from her husband, Macbeth, informing her about the witches" prophecies on the possibility of Kingship. A variety of well-known topics are explored, including the revelation of the true traits of characters such as Macbeth and Lady Macbeth. "Glamis thou art, and Cawdor, and shalt be What thou art promised; yet do I fear thy nature, It is too full o'th"milk of human kindness To catch the nearest way. Thou wouldst be great, Art not without ambition, but without The illness should attend it. What thou wouldst highly, That wouldst thou holily; wouldst not play false, And yet wouldst strongly win. Thou"dst have, great Glamis, That which cries, "Thus who must do" if thou have it; And that which rather thou dost fear to do. Than wishest should be undone. Hie thee hither, That I may pour my spirits in thine ear And chastise with the valour of my tongue All that impedes thee from the golden round, Which fate and metaphysical aid doth seem To have crowned thee withal." -Lady Macbeth, Act 1 Sc5, Lines 13 - 28 Her first thoughts are based on the reaction of the realism of Macbeth being Thane of Glamis, and possibly Cawdor as the witches predicted. This is expressed through the words "What thou art promised". The idea of having soliloquy interacting with the witches" predictions creates a sense of spirituality. This being Lady Macbeth's first appearance in the play is effective as it allows the reader to associate this sense of spirituality and evil with her character, that has yet to have any substance to allow the reader to interpret her role by. She continues by expressing her fear over not being able to "catch the nearest way" due to Macbeth's overly kind character. This is demonstrated through a variety of techniques. For example, Lady Macbeth explains how her husband would "not play false" nor would he "wrongly win".
