Philo Judaeus Quod Deterius Potiori Insidiari Soleat 75

[75] For as, when some musician or grammarian is dead, the music and grammar which existed in them dies with them, but their ideas survive, and in a manner live as long as the world itself endures; according to which the existing race of men, and those who are to exist hereafter in continual succession, will, to the end of time, become skilful in music and grammar. Thus, also, if the prudence, or the temperance, or the courage, or the justice, or, in short, if the wisdom of any kind existing in any individual be destroyed, nevertheless the prudence existing in the nature of the immortal universe will still be immortal; and every virtue is erected like a pillar in imperishable solidity, in accordance with which there are some good people now, and there will be some hereafter.
