With Sonnet 115 William Shakespeare turns his attention to the perplexing paradox that a love that is experienced as complete and absolute and therefore perfect, such as his love for his young man, may turn out, over time, to have been but a fledgling infant compared to the even fuller, more profound, more mature love that it has the potential to grow into.

In acknowledging that love can evolve and grow over time it sets the premise that love itself is changeable – here for the better, to be more deeply and more sincerely felt than ever before – and it therefore not only concedes, but claims as a lover's right, the necessity, perhaps, to revise statements made about love in the past, and in doing so to effectively give those pronouncements the lie.

With his curiously cryptic Sonnet 114, William Shakespeare poses a rhetorical question to his younger lover, asking whether his experience of seeing him in everything he looks at is down simply to his eye flattering him, or to his eye having acquired the ancient mystical art of alchemy and actually turning even ugly creatures into beautiful angelic beings just such as the young man himself.

He then also settles the matter emphatically and declares without reservation that it is indeed flattery on the eye's part that has this effect on him, but that any sin the mind may be committing in lapping it all up is mitigated by the fact that the eye too loves what it wants to see – the young man's beauty – and so willingly tastes of this flattering, though therefore potentially poisonous, potion first, before passing it on for the mind to metaphorically imbibe.

With Sonnet 113, William Shakespeare returns once more to the theme of separation, reflecting on how, when he is away from his younger lover, everything he sees takes on his lover's shape and thus reminds him of him.

Although we don't know when exactly the sonnet was written and therefore where precisely in the collection it belongs, it would appear to also, therefore, pick up on the notion, emphatically expressed in the previous sonnet, of his lover being his 'all the world', and it certainly also connects strongly to the sonnet that follows, which will further elaborate on the idea that the younger man with his beauty turns even the ugliest appearance to loveliness in Shakespeare's mind.
