We would wish to discover the Plan of the Universe, and the means employed by the Eternal Architect in the execution of his magnificent design.
But, are the faculties of our nature equal to this? and what are the principles which ought to guide us in these researches?
We will found our hypothesis in the general laws of motion, whose effects are every where the same, and whose influence extends to the utmost limits of matter.
About this person
Johann Heinrich Lambert was born in the Republic of Mulhouse - then allied to the Swiss Confederacy - on 26 or 28 August 1728. He ranged across mathematics, physics, philosophy, astronomy, and cartography, making contributions that outlasted the century. His work in optics reshaped how light was understood; his advances in map projections changed how the world was drawn. He died in Berlin on 25 September 1777, not yet fifty, with problems still unsolved on his desk.
