Thus with the question of the Being of truth and the necessity of presupposing it, just as with the question of the essence of knowledge, an 'ideal subject' has generally been posited. The motive for this, whether explicit or tacit, lies in the requirement that philosophy should have the '*a priori*' as its theme, rather than 'empirical facts' as such. There is some justification for this requirement, though it still needs to be grounded ontologically. Yet is this requirement satisfied by positing an 'ideal subject'? Is not such a subject *a fanciful idealization*? With such a conception have we not missed precisely the *a priori* character of that merely 'factual' subject, Dasein? Is it not an attribute of the *a priori* character of the factical subject (that is, an attribute of Dasein's facticity) that it is in the truth and in untruth equiprimordially?The ideas of a 'pure "I"' and of a 'consciousness in general' are so far from including the *a priori* character of 'actual' subjectivity that the ontological characters of Dasein's facticity and its state of being are either passed over or not seen at all. Rejection of a 'consciousness in general' does not signify that the *a priori* is negated, any more than the positing of an idealized subject guarantees that Dasein has an *a priori* character grounded upon fact.Both the contention that there are 'eternal truths' and the jumbling together of Dasein's phenomenally grounded 'ideality' with an idealized absolute subject, belong to those residues of Christian theology within philosophical problematics which have not as yet been radically extruded.The Being of truth is connected primordially with Dasein. And only because Dasein is as constituted by disclosedness (that is, by understanding), can anything like Being be understood; only so is it possible to understand Being."―from_Being and Time_.

Thus Epicurus also, when he designs to destroy the natural fellowship of mankind, at the same time makes use of that which he destroys.For what does he say? ‘Be not deceived, men, nor be led astray, nor be mistaken: there is no natural fellowship among rational animals; believe me. But those who say otherwise, deceive you and seduce you by false reasons.’—What is this to you? Permit us to be deceived.Will you fare worse, if all the rest of us are persuaded that there is a natural fellowship among us, and that it ought by all means to be preserved? Nay, it will be much better and safer for you.Man, why do you trouble yourself about us? Why do you keep awake for us? Why do you light your lamp? Why do you rise early? Why do you write so many books, that no one of us may be deceived about the gods and believe that they take care of men; or that no one may suppose the nature of good to be other than pleasure?For if this is so, lie down and sleep, and lead the life of a worm, of which you judged yourself worthy: eat and drink, and enjoy women, and ease yourself, and snore.And what is it to you, how the rest shall think about these things, whether right or wrong? For what have we to do with you?You take care of sheep because they supply us with wool and milk, and last of all with their flesh. Would it not be a desirable thing if men could be lulled and enchanted by the Stoics, and sleep and present themselves to you and to those like you to be shorn and milked?For this you ought to say to your brother Epicureans: but ought you not to conceal it from others, and particularly before every thing to persuade them, that we are by nature adapted for fellowship, that temperance is a good thing; in order that all things may be secured for you?Or ought we to maintain this fellowship with some and not with others? With whom then ought we to maintain it?With such as on their part also maintain it, or with such as violate this fellowship?And who violate it more than you who establish such doctrines?What then was it that waked Epicurus from his sleepiness, and compelled him to write what he did write?
