love alters not with his brief hours and weeks,

but bears it out even to the edge of doom.

If this be error, and upon me proved,

I never writ, nor no man ever loved.

A Laura y Daniel,

a quienes pertenece el futuro.

In memoriam:

A Manuel Tuñón de Lara,

a Herbert Rutledge Southworth,

maestros en historia

y en amistad.

A Juan Negrín:

Un luchador, no un abandonista
