The writer says: I have composed this work not to teach people what they do not know but to remind them of what they already know and which is very familiar to them. For you will find in most of my words only things which most people already know and do not have any doubt about.
אָמַר הַמְחַבֵּר: הַחִבּוּר הַזֶּה לֹא חִבַּרְתִּיו לְלַמֵּד לִבְנֵי הָאָדָם אֶת אֲשֶׁר לֹא יָדְעוּ, אֶלָּא לְהַזְכִּירָם אֶת הַיָּדוּעַ לָהֶם כְּבָר וּמְפֻרְסָם אֶצְלָם פִּרְסוּם גָּדוֹל. כִּי לֹא תִּמְצָא בְּרוֹב דְּבָרַי, אֶלָּא דְּבָרִים שֶׁרֹב בְּנֵי הָאָדָם יוֹדְעִים אוֹתָם וְלֹא מִסְתַּפְּקִים בָּהֶם כְּלָל.
