Arthur Schopenhauer
Publisher: Dover Publications (2006)

When you say I, I, I want to exist, it is not you alone that says this.  Everything says it, absolutely everything that has the faintest trace of consciousness.  It follows, then, that this desire of yours is just the part of you that is not individual - the part that is common to all things without distinction.  It is the cry, not of the individual, but of existence itself; it is the intrinsic element in everything that exists, nay it is the cause of anything existing at all.
