I am only about half alive - a large part of my strength is consumed in sitting up or walking. My nervous system is a shattered wreck, and I am absolutely bored & listless save when I come upon something which peculiarly interests me. However - so many things do interest me, & interest me intensely, in science, history, philosophy, & literature; that I have never actually desired to die, or entertained any suicidal designs, as might be expected of one with so little kinship to the ordinary features of life.
What is at issue is the conversion of the mind from the twilight of error to the truth, that climb up into the real world which we shall call true philosophy.
In Philosophy, the contemplations of man do either penetrate unto God, or are circumferred to Nature, or are reflected and reverted upon himself. Out of which several inquiries there do arise three knowledges, Divine Philosophy, Natural Philosophy, and Human Philosophy or Humanity. For all things are marked and stamped with this triple character of the power of God, the difference of Nature and the use of Man.
The sum total of all possible knowledge of God is not possible for a human being, not even through a true revelation. But it is one of the worthiest inquiries to see how far our reason can go in the knowledge of God.
I do not wish you much happiness--it would bore you; I do not wish you trouble either; but, following the people's philosophy, I will simply repeat: 'Live more' and try somehow not to be too bored; this useless wish I am adding on my own.
An imbecile habit has arisen in modern controversy of saying that such and such a creed can be held in one age but cannot be held in another. Some dogma, we are told, was credible in the twelfth century, but is not credible in the twentieth. You might as well say that a certain philosophy can be believed on Mondays, but cannot be believed on Tuesdays. You might as well say of a view of the cosmos that it was suitable to half-past three, but not suitable to half-past four. What a man can believe depends upon his philosophy, not upon the clock or the century.
Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation, all which may be guides to an outward moral virtue, though religion were not; but superstition dismounts all these, and erects an absolute monarchy in the minds of men.
The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.
But the idols of the Market Place are the most troublesome of all: idols which have crept into the understanding through their alliances with words and names. For men believe that their reason governs words. But words turn and twist the understanding. This it is that has rendered philosophy and the sciences inactive. Words are mostly cut to the common fashion and draw the distinctions which are most obvious to the common understanding. Whenever an understanding of greater acuteness or more diligent observation would alter those lines to suit the true distinctions of nature, words complain.
