"One day when I, Porphyrius, was meditating about taking my own life, Plotinus guessed my intention. He interrupted me, and said that such a design could not proceed from a healthy mind, but was due to some melancholy indisposition, and that I must have change of air" (Ex. _Life of Plotinus_, by Porphyrius). The same incident is recounted in the life of Plotinus by Eunapius, who adds that Plotinus recorded in a book the conversation he then held with Porphyrius on the subject. _Plotinus_. You know, Porphyrius, how sincerely I am your friend. You will not wonder therefore that I am unquiet about you. For some time I have noticed how sad and thoughtful you are; your expression of countenance is unusual, and you have let fall certain words which make me anxious. In short, I fear that you contemplate some evil design. _Porphyrius_. How! What do you mean? _Plotinus_. I think you intend to do yourself some injury; it were a bad omen to give the deed its name. Listen to me, dear Porphyrius, and do not conceal the truth. Do not wrong the friendship that has so long existed between us. I know my words will cause you displeasure, and I can easily understand that you would rather have kept your design hid. But I could not be silent in such a matter, and you ought not to refuse to confide in one who loves you as much as himself. Let us then talk calmly, weighing our words. Open your heart to me. Tell me your troubles, and let me be auditor of your lamentations. I have deserved your confidence. I promise, on my part, not to oppose the carrying out of your resolution, if we agree that it is useful and reasonable. _Porphyrius_. I have never denied a request of yours, dear Plotinus. I will therefore confess to you what I would rather have kept to myself; nothing in the world would induce me to tell it to anyone else. You are right in your interpretation of my thoughts. If you wish to discuss the subject, I will not refuse, in spite of my dislike to do so; for on such occasions the mind prefers to encompass itself with a lofty silence, and to meditate in solitude, giving itself up for the time to a state of complete self-absorption. Nevertheless, I am willing to do as you please.
