“This is a day of great events. We can pay tribute to our State President and to our Republic.”
“It is not events and the things one sees and enjoys that produce happiness, but a state of mind which can endow events with its own quality, and we must hope for the duration of this state rather than the recurrence of pleasurable events. Is this state actually an interior one, and can we recognize it otherwise than the by the changes it produces in all exterior things? If we exclude sensation and memory from our thoughts, there is nothing left but a wordless emptiness. Where can pure ecstasy and pure happiness be found? As certain phosphorescent fish see the deep water, the seaweed, and the other creatures of the sea light up at their approach but never perceive the movable source of this illumination because it is in themselves, so the happy man, though he is aware of his effect upon others, has difficulty in perceiving his happiness and even greater difficulty in predicting it.”

                                        K-Linesː A Theory of Memory (1980) 
Context: A memory should induce a state through which we see current reality as an instance of the remembered event — or equivalently, see the past as an instance of the present.... the system can perform a computation analogous to one from the memorable past, but sensitive to present goals and circumstances.

                                    “After death the sensation is either pleasant or there is none at all. But this should be thought on from our youth up, so that we may be indifferent to death, and without this thought no one can be in a tranquil state of mind. For it is certain that we must die, and, for aught we know, this very day. Therefore, since death threatens every hour, how can he who fears it have any steadfastness of soul?”
                                
                                
                                
                                
                                    
                                    Post mortem quidem sensus aut optandus aut nullus est. Sed hoc meditatum ab adulescentia debet esse mortem ut neglegamus, sine qua meditatione tranquillo animo esse nemo potest. Moriendum enim certe est, et incertum an hoc ipso die. Mortem igitur omnibus horis impendentem timens qui poterit animo consistere?
