Key Citations On Confidence

1. PD12: A man cannot dispel his fear about the most important matters if he does not know what is the nature of the universe, but suspects the truth of some mythical story. So that, without natural science, it is not possible to attain our pleasures unalloyed.
2. PD13: There is no profit in securing protection in relation to men, if things above, and things beneath the earth, and indeed all in the boundless universe, remain matters of suspicion.
3. VS34. It is not so much our friends' help that helps us, as it is the confidence of their help.
4. PD04: As many as possess the power to procure complete immunity from their neighbors, these also live most pleasantly with one another, since they have the most certain pledge of security, and, after they have enjoyed the fullest intimacy, they do not lament the previous departure of a dead friend, as though he were to be pitied.
5. Epicurus to Herotodus [83]: Here, Herodotus, is my treatise on the chief points concerning the nature of the general principles, abridged so that my account would be easy to grasp with accuracy. I think that, even if one were unable to proceed to all the detailed particulars of the system, he would from this obtain an unrivaled strength compared with other men. For indeed he will clear up for himself many of the detailed points by reference to our general system, and these very principles, if he stores them in his mind, will constantly aid him. For such is their character that even those who are at present engaged in working out the details to a considerable degree, or even completely, will be able to carry out the greater part of their investigations into the nature of the whole by conducting their analysis in reference to such a survey as this. And as for all who are not fully among those on the way to being perfected, some of them can from this summary obtain a hasty view of the most important matters without oral instruction so as to secure peace of mind.
