さらに続けて，これら第一の真理からわたしが演縛したほかの真理の連鎖全体をここで示していきたいのはやまやまだが，そのためには，学者たちのあいだで論争中の多くの問題について語ることがいま必要になってくる。わたしはこれらの学者たちといざこざを起こしたくないので，そうしたことは差し控え，ただ概括的にこれらの問題がどんなものかを述べるにとどめるほうがよいと思う。公衆がこれらの問題をもっと詳しく知ることが有益かどうか，もっと賢明な人たちに判断してもらうためである。わたしは，神の存在と魂の存在を証明するために，いま用いた原理以外は何も想定しないと決意し，また以前に幾何学者の論証が明断で確実だと思われた以上に明断で確実だと思われないものは，何も真として受け入れないと決意し，それをつねに堅く守ってきた。それにもかかわらず，思いきって言おう。わたしは哲学で取り扱うならわしになっている主要な難問すべてについて，わたし自身を満足させるようなやり方をわずかな時間で見いだし，そればかりでなく，いくつかの法則をも認めたのだ。これらの法則は，神が自然のなかにしっかりと定め，かつその概念をわれわれの魂のなかに強く刻みこんだので，十分に反省を加えれば，世界に存在し生成するすべてのものにおいて，それらの法則が正確に守られているのを疑いえないのである。次に，これらの法則の帰結を考察して，それまでに学んだすべてのこと，そればかりか学びたいと望んでいたすべてのことよりも，有益で重要な多くの真理を発見したと思われる。
I WOULD here willingly have proceeded to
exhibit the whole chain of truths which I
deduced from these primary; but as with a
view to this it would have been necessary
now to treat of many questions in dispute
among the learned, with whom I do not wish
to be embroiled, I believe that it will be
better for me to refrain from this exposition,
and only mention in general what these truths
are, that the more judicious may be able
to determine whether a more special account
of them would conduce to the public advantage.
I have ever remained firm in my original
resolution to suppose no other principle
than that of which I have recently availed
myself in demonstrating the existence of
God and of the soul, and to accept as true
nothing that did not appear to me more clear
and certain than the demonstrations of the
geometers had formerly appeared; and yet
I venture to state that not only have I found
means to satisfy myself in a short time on
all the principal difficulties which are
usually treated of in Philosophy, but I have
also observed certain laws established in
nature by God in such a manner, and of which
he has impressed on our minds such notions,
that after we have reflected sufficiently
upon these, we cannot doubt that they are
accurately observed in all that exists or
takes place in the world: and farther, by
considering the concatenation of these laws,
it appears to me that I have discovered many
truths more useful and more important than
all I had before learned, or even had expected
to learn.
