I find no evidence that Jefferson read Spinoza, although his library does contain a copy of his works. Enlightenment thought is so saturated with Spi… - Benedictus de Spinoza

In the history of philosophy we meet with Substance as the principle of Spinoza's system. On the import and value of this much-praised and no-less decried philosophy there has been great misunderstanding and a deal of talking since the days of Spinoza. The atheism, and as a further charge, the pantheism of the system has formed the commonest ground of accusation. These cries arise because of Spinoza's conception of God as substance, and substance only. What we are to think of this charge follows, in the first instance, from the place which substance takes in the system of the logical idea. Though an essential stage in the evolution of the idea, substance is not the same with absolute idea, but the idea under the still limited form of necessity.

لقد أُوحيَت كلُّ المقاييس إلى سُليمان بوسائل على مُستوى فَهْمِه وطبقًا لآرائه؛ ذلك لأنه، نظرًا إلى أننا غير مُلزَمين بالاعتقاد بأنَّ سليمان كان رياضيًّا، فمن حقِّنا أن نؤكِّد أنه كان يجهَلُ نِسبة مُحيط الدائرة إلى قُطرها، وكان يظنُّ مع جمهرة العُمَّال أنها نسبة ٣ إلى ١، فإذا قيل إنَّنا لم نفهم نصَّ سِفر الملوك (٧: ٢٣) فإني لا أعلم، في الحق، ماذا يُمكننا أن نفهم من الكتاب؛ ذلك لأنَّ ما ورَد في هذا الموضع كان مُجرَّد وصفٍ للبناء، وعلى نحوٍ تاريخي مَحْض. أمَّا إذا اعتقَدَ أحدٌ أنه يستطيع افتراضَ قصْدٍ آخر للكِتاب لم يُصرَّح به لسبب نجهله، فإنَّ هذا أمرٌ لا يترتَّب عليه أقلُّ من أن نقلِبَ الكتاب بأسره رأسًا على عقب

The only successful attempt to free human reason from the authority of religion was that of Spinoza (1632–1677). In his Theologico-Political Treatise (1670) he denied the claims for divine authority based on the text of Scripture and religious tradition. [...] Spinoza was the first secular Jew, and as such, the first secular man. Indeed, he served as the role model for all secular Jews, instituting the precise features that characterized future Jewish secularists.
