translation	copyright	©	2017	by	David	Forman "The	Horizon	of	Everything	Human	..."	(1693–1701?)1,2 by	G.	W.	Leibniz,	translated	by	David	Forman (2017/7/31) The	horizon	of	everything	human	or	a	demonstration:	that	the	number	of	truths	or	falsehoods enunciable	[enuntiabilis]	by	humans	as	they	are	now	is	limited;	and	also	that	if	the	present condition	of	humanity	persisted	long	enough,	it	would	happen	that	the	greatest	part	of	what they	would	communicate	in	words,	whether	by	talking	or	writing,	would	have	to	coincide	with what	others	have	already	communicated	in	the	past;	and	moreover	that	new	humans	would lead	an	entire	life	that	appears	thoroughly	the	same	to	the	senses	as	lives	that	others	have already	led. Archimedes,	whose	greatness	was	recognized	by	King	Hiero	of	Sicily,	aroused	the	admiration	of the	king	and	the	court	by	saying	not	only	that	the	number	of	grains	of	sand	is	not	infinite,	but also	that	it	would	be	easy	to	express	[enuntiare]	a	number	much	larger	than	that	which	all	the grains	of	sand	would	reach	if	the	space	from	the	earth	to	the	stars	were	filled	with	sand.	He demonstrated	this	in	a	book	that	is	still	extant.3	But	what	is	the	number	of	grains	of	sand compared	to	the	number	of	enunciable	truths	and	falsehoods?	For	there	is	no	grain	of	sand that	would	not	be	able	to	supply	many	truths	and	falsehoods	of	this	sort,	all	of	which	would	be included	in	the	reckoning-to	say	nothing	of	the	innumerable	expressions	concerning	other objects.	And	yet	a	number	that	would	exceed	the	number	of	all	these	expressions	can	be	easily expressed	and	comprehend;	which	I	will	now	show. Finally,	so	that	these	conclusions	will	be	less	vulnerable	to	difficulties,	I	declare	that	I	speak	only of	enunciable	propositions:	for	I	do	not	deny	that	men	have	and	can	have	a	great	many confused	thoughts	and	sensations,	impressions,	fantasies,	and	dreams	that	cannot	be enunciated.	Indeed,	it	is	certain	that	there	are	not	enough	words	sufficient	for	us	to	express	all the	subtle	differences	among	sensible	qualities,	such	as	colors,	sounds,	odors,	tastes,	and touches;	and	also	among	internal	senses,	desires,	and	pleasures	and	pains;	which	are	also greatly	varied	both	by	the	change	of	objects	and	by	our	own	everyday	change. 1	LH	IV,	vol.	V,	9,	Bl.	1.	The	Latin	text	of	this	undated	fragment	is	transcribed	in	M.	Fichant	(ed.),	De	l'	Horizon	de la	Doctrine	Humaine	(1693);	Ἀποκατάστασις	πάντων	(La	Restitution	universelle)	(1715),	(Paris:	J.	Vrin,	1991),	pp.54, 56.	Fichant	provides	a	French	translation	(pp.	55,	57),	which	I	have	consulted	in	preparing	the	present	translation. 2	Leibniz's	original	title	was	"Horizon	doctrinae	humanae"	("The	Horizon	of	Human	Knowledge").	This	matches the	title	of	the	longer	"De	l'Horizon	de	la	Doctraine	Humaine"	from	no	later	than	1693;	see	Fichant,	pp.	39–53. Leibniz	later	added	"actionisque"	("and	action")	to	this	title,	and	then	finally	settled	on	title	given	here,	"Horizon rerum	humanarum	..."	(see	Fichant,	pp.	15-16).	This	suggests	that	the	fragment	stems	from	the	period	1693-1701. 3	Namely,	the	Psammites,	known	in	Latin	as	Arenarius	and	in	English	as	The	Sand	Reckoner. 54
