Seneca · On good company
Letters 62.2
When I give myself to my friends, I do not withdraw from my own company, nor do I linger with those who are associated with me through some special occasion or some case which arises from my official position. But I spend my time in the company of all the best; no matter in what lands they may have lived, or in what age, I let my thoughts fly to them.
Seneca, Letters to Lucilius 62.2, translated by Richard Mott Gummere
