Gaiety is a quality of ordinary men. Genius always presupposes some disorder in the machine.
Interpretation
Genius often stems from imperfections, while joy is a trait found in everyone.
Denis Diderot's quote suggests that while ordinary people can experience joy and gaiety, genius is often accompanied by a certain level of chaos or disorder. This implies that those who think outside the box or create something extraordinary may demonstrate an unconventional approach or mindset that deviates from the norm.

The arbitrary rule of a just and enlightened prince is always bad. His virtues are the most dangerous and the surest form of seduction: they lull a people imperceptibly into the habit of loving, respecting, and serving his successor, whoever that successor may be, no matter how wicked or stupid.
This root [the potato], no matter how much you prepare it, is tasteless and floury. It cannot pass for an agreeable food, but it supplies a food sufficiently abundant and sufficiently healthy for men who ask only to sustain themselves. The potato is criticized with reason for being windy, but what matters windiness for the vigorous organisms of peasants and laborers?
Do you see this egg? With this you can topple every theological theory, every church or temple in the world.

If at the heart of one's being, there is no self to which one ought to be true, then sincerity is simply nerve; it lies in the unabashed vigor of the pretense. But pretense is only pretense when it is assumed that the act is not true to the agent. Find the agent.
Nothing would catch me off guard, because I understand the world I live in. I understand it very well. And the world I live in is not necessarily a fair or just world. I have dealt with these injustices for the bigger part of my life.
A critic is to an author as a fungus to an oak.
Grace is more than mercy and love. It super-adds to them. It denotes, not simply love, but the love of a sovereign, transcendent Superior. One that may do what He will. That may wholly choose whether He will love or no. Now God, who is an infinite Sovereign, who might have chosen whether ever He would love us or no; for Him to love us, this is Grace.
Reach me a gentian, give me a torch! Let me guide myself with the blue, forked torch of a flower down the darker and darker stairs, where blue is darkened on blueness even where Persephone goes, just now, from the frosted September to the sightless realm where darkness is awake upon the dark.
War is not a life: it is a situation, one which may neither be ignored nor accepted.
