Nostalgia

Nostalgia began life as a diagnosis — homesickness named as an illness in seventeenth-century Swiss soldiers — and the reading keeps that origin in mind, because it explains the emotion's doubleness. Nostalgia is not simple fondness; it is fondness shot through with the knowledge that the thing remembered is gone, and the writers worth following have held both halves without collapsing one into the other.

The reading is densest in the memoir of place and time. Vladimir Nabokov's Speak, Memory is the modern reference for nostalgia made precise rather than soft — the lost Russia of childhood rendered in such exact detail that the loss becomes sharp rather than warm. The memoir of a vanished world — an immigrant's first country, a childhood landscape paved over — reads nostalgia as a form of keeping faith with what shaped the self. The contemplative inheritance touches it too, in the long literature of exile and return, of the garden that cannot be re-entered, of a home the soul keeps reaching back toward.

Nostalgia is not the same as longing, grief, or sentimentality. Longing reaches toward something distant that might still be reached; nostalgia reaches toward something that is gone by definition. Grief mourns a specific absent person or thing; nostalgia mourns a whole texture of being that included the self who felt it. Sentimentality wants the warmth without the loss; nostalgia knows the loss is the price of the warmth. The four are kin and the reading keeps them apart, because nostalgia's defining feature is that the sweetness and the ache are the same feeling.
