'the unfathomed distances in himself'

From the first, the baby stirred in the young father a deep, strong emotion he dared scarcely acknowledge, it was so strong and came out of the dark of him. When he heard the child cry, a terror possessed him, because of the answering echo from the unfathomed distances in himself. Must he know in himself such distances, perilous and imminent?

—D.H. Lawrence, The Rainbow (1915)

'the only true thing in life'

Fatherhood, in the sense of conscious begetting, is unknown to man. It is a mystical estate, an apostolic succession, from only begetter to only begotten. On that mystery and not on the madonna which the cunning Italian intellect flung to the mob of Europe the church is founded and founded irremovably because founded, like the world, macro- and microcosm, upon the void. Upon incertitude, upon likelihood. Amor matris, subjective and objective genitive, may be the only true thing in life. Paternity may be a legal fiction. Who is the father of any son that any son should love him or he any son?

—James Joyce, Ulysses (1922)
