“Truth is the daughter of time, and I feel no shame in being her midwife.”
Temporis filia veritas; cui me obstetricari non pudet.
As quoted in The Ismailis in the Middle Ages: A History of Survival, A search for Salvation (2007) by Shafique N. Virani, p. 28

Literary and Historical Miscellanies (1855), The Necessity, the Reality, and the Promise of the Progress of the Human Race (1854)
Context: No science has been reached, no thought generated, no truth discovered, which has not from all time existed potentially in every human mind. The belief in the progress of the race does not, therefore, spring from the supposed possibility of his acquiring new faculties, or coming into the possession of a new nature.
Still less does truth vary. They speak falsely who say that truth is the daughter of time; it is the child of eternity, and as old as the Divine mind. The perception of it takes place in the order of time; truth itself knows nothing of the succession of ages. Neither does morality need to perfect itself; it is what it always has been, and always will be. Its distinctions are older than the sea or the dry land, than the earth or the sun. The relation of good to evil is from the beginning, and is unalterable.

“Another ancient poet, whose name I have forgotten, said that Truth is the daughter of Time.”
Noctes Atticae, XII, 11, 7.
Original: (la) Alius quidam veterum poetarum, cuius nomen mihi nunc memoriae non est, Veritatem Temporis filiam esse dixit.
