Danh ngôn của Miguel de Unamuno (Sứ mệnh: 4)

Love is the child of illusion and the parent of disillusion.
Art distills sensations and embodies it with enhanced meaning.
It is sad not to love, but it is much sadder not to be able to love.
Man dies of cold, not of darkness.
Life is doubt, and faith without doubt is nothing but death.
That which the Fascists hate above all else, is intelligence.
Science is a cemetery of dead ideas.
There is no true love save in suffering, and in this world we have to choose either love, which is suffering, or happiness. Man is the more man - that is, the more divine - the greater his capacity for suffering, or rather, for anguish.
Faith which does not doubt is dead faith.
True science teaches, above all, to doubt and to be ignorant.
It is truer to say that martyrs create faith more than faith creates martyrs.
A man does not die of love or his liver or even of old age; he dies of being a man.
If it is nothingness that awaits us, let us make an injustice of it; let us fight against destiny, even though without hope of victory.
