Anxiety is a sickness of the human spirit rather than of the psyche alone.

Anxiety is the infinite which everyone is in touch with.

Anxiety is the reality of freedom as possibility anterior to possibility.

Anxiety is the only emotion that does not deceive.

Curiosity is the kernel of the forbidden fruit.

Curiosity is the direct incontinency of the spirit.

Curiosity is, as neugierig, an avarice (gier) of the new (neu), an everyday tendency of Dasein to let itself be restlessly carried along solely by the way the world appears.

Curiosity is a search for novelty and endless stimulation rather than belonging or dwelling.

Excitement is really just jealousy of your future self.

Excitement is the drunkenness of the spirits. Only calm waters reflect heaven in their bosom.

Excitement is a state which sometimes prevents genuine happiness.

The Idea is like a shadow; substantial enough until we try to grasp it.

An Idea is nothing unless it is public — Ideas are not truly alive if they remain locked in a single mind.

An Idea is like a child. No matter how much you like other people's, you can't help thinking your own are best.

The Idea , when new, hurts some minds for the same reason as new shoes hurt some feet.
