Fourier predicted that the ideal world he would help to create would last 80,000 years, 8,000 of them in an era of Perfect Harmony in which:
- Androgynous plants would copulate
- Six moons would orbit the earth
- The North Pole would be milder than the Mediterranean
- The seas would lose their salt and become oceans of lemonade
- The world would contain 37 million poets equal to Homer, 37 million mathematicians equal to Newton and 37 million dramatists equal to Molière, although "these are approximate estimates"
- Every woman would have four lovers or husbands simultaneously
