The greatest wisdom is to make the enjoyment of the present the supreme object of life; because that is the only reality, all else being merely the play of thought. On the other hand, such a course might just as well be called the greatest folly: for that which in the next moment exists no more, and vanishes utterly, like a dream, can never be worth a serious effort.
To attain something desired is to discover how vain it is; and…though we live all our lives in expectation of better things, we often at the same time long regretfully for what is past. The present, on the other hand, is regarded as something quite temporary and serving only as the road to our goal. That is why most men discover when they look back on their life that they have the whole time been living ad interim, and are surprised to see that which they let go by so unregarded and unenjoyed was precisely their life, was precisely in expectation of which they lived.
For an author to write as he speaks is just as reprehensible as the opposite fault, to speak as he writes; for this gives a pedantic effect to what he says, and at the same time makes him hardly intelligible.
Faith is like love, it cannot be forced. Therefore it is a dangerous operation if an attempt be made to introduce or bind it by state regulations; for, as the attempt to force love begets hatred, so also to compel religious belief produces rank unbelief.
Every man takes the limits of his own field of vision for the limits of the world. This is an error of the intellect as inevitable as that error of the eye which lets you fancy that on the horizon heaven and earth meet.
Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.
Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains
in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.
Poetry is related to philosophy as experience is related to empirical science. Experience makes us acquainted with the phenomenon in the particular and by means of examples, science embraces the whole of phenomena by means of general conceptions. So poetry seeks to make us acquainted with the Platonic Ideas through the particular and by means of examples. Philosophy aims at teaching, as a whole and in general, the inner nature of things which expresses itself in these. One sees even here that poetry bears more the character of youth, philosophy that of old age.
