Introduction to the History of Hebrew Philosophy

...[intellectual] source original: [li]mitatum fontem. The fragment completes a thought from the previous page regarding the source of knowledge found within the mind., and shows that it must be sought in the innermost recesses of our mind. It teaches that all other matters should be handled as the condition of human life demands, neither forbidding what is necessary, nor approving what is superficial or harmful. This is that simplicity of philosophy philosophia and true wisdom sapientia from which, if those who wish to be seen as its practitioners did not depart, the human race would be remarkably well-served.

But as soon as the human intellect leaps over these established limits and indulges in contemplations that are more subtle and profound than is fitting, one can expect nothing else from that source but errors, heresies haereses, disputes, and a vast army of evils. And this shall be my primary aim, this the fruit of all my labors: that mortals, warned at last by so many examples, may learn not to grant too much to the powers of their own intellect, nor to fly out further than the reason ratio of the human weakness that surrounds us permits.

For it will be clearly established from this entire history of philosophy historia philosophiae which I am now producing, that the sects and errors, and whatever a person of sound judgment original: vir cordatus detests among the tribe of philosophers—and even the very heresies within the Church—have arisen from no other source than that mortals dared to overstep these boundaries established by nature. For the rest, as I have dedicated myself entirely to the world of letters original: rei litterariae; referring to the collective body of scholarly work and the community of "the Republic of Letters", I pray to God that these efforts of mine, such as they are, may yield a prosperous and happy result.
