Shakespeare compares a beloved person to the things that keep us alive—food and life-giving rain. But the calm assurance that image suggests quickly unravels. The speaker’s inner state is a constant tug-of-war, like a miser who one moment swells with pride over his treasure and the next panics that time will steal it. That restless energy runs through the whole poem: at times he wants to be completely alone with you, then suddenly he wants the whole world to witness his joy. He swings from gorging himself on the mere sight of you to feeling utterly starved for another glance. Every delight he knows is tied to your presence, so when you’re not there, nothing else satisfies. The mood is obsessive and almost exhausting—no middle ground, just a cycle of pining and overindulgence. The final line nails that all-or-nothing hunger: he’s either devouring everything at once or left with nothing at all.
Sonnet 75: So are you to my thoughts as food to life — Summary
So are you to my thoughts as food to life, Or as sweet-season'd showers are to the ground; And for the peace of you I hold such strife As 'twixt a miser and his wealth is found. Now proud as an enjoyer, and anon Doubting the filching age will steal his treasure; Now counting best to be with you alone, Then better'd that the world may see my pleasure: Sometime all full with feasting on your sight, And by and by clean starved for a look; Possessing or pursuing no delight, Save what is had, or must from you be took. Thus do I pine and surfeit day by day, Or gluttoning on all, or all away.
