Entia non sunt multiplicanda praeter necessitatem (Entities must not be multiplied beyond necessity.)
The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity. The creative mind plays with the objects it loves.
Necessity never made a good bargain.
In an industrial society which confuses work and productivity, the necessity of producing has always been an enemy of the desire to create.
Necessity is the plea for every infringement of human freedom. It is the argument of tyrants; it is the creed of slaves.
Where there is much desire to learn, there of necessity will be much arguing, much writing, many opinions; for opinions in good men is but knowledge in the making.
