There are ages in which the rational man and the intuitive man stand side by side, the one in fear of intuition, the other with scorn for abstraction. The latter is just as irrational as the former is inartistic. They both desire to rule over life: the former, by knowing how to meet his principle needs by means of foresight, prudence, and regularity; the latter, by disregarding these needs and, as an "overjoyed hero," counting as real only that life which has been disguised as illusion and beauty.
Friedrich Nietzsche

Yes perhaps, as the Sage says, "nothing worthy of proving can be proven, nor yet disproven"; but can we restrain that instinct which urges man to wish to know, and above all to wish to know the things which conduce to life, to eternal life? Eternal life, not eternal knowledge as the Alexandrian gnostic said. For living is one thing and knowing is another; and... perhaps there is an opposition between the two that we may say that everything vital is anti-rational, not merely irrational, and that everything rational is anti-vital. And this is the basis of the tragic sense of life.
Miguel de Unamuno
Science does not give Don Quixote what he demands of it. "Then let him not make the demand," it will be said, "let him resign himself, let him accept life and truth as they are." But he does not accept them as they are, and he asks for signs, urged thereto by Sancho, who stands by his side. And it is not that Don Quixote does not understand what those understand who talk thus to him, those who succeed in resigning themselves and accepting rational life and rational truth. No, it is that the needs of his heart are greater. Pedantry? Who knows!... And he wishes, unhappy man, to rationalize the irrational and irrationalize the rational. And he sinks into despair of the critical century whose two greatest victims were Nietzsche and Tolstoi. And through this despair he reaches the heroic fury of which Giordano Bruno spoke — that intellectual Don Quixote who escaped from the cloister — and became an awakener of sleeping souls (dormitantium animorum excubitor), as the ex-Dominican said of himself — he who wrote: "Heroic love is the property of those superior natures who are called insane (insano) not because they do not know, but because they over-know (soprasanno)."
Miguel de Unamuno
The central psychological endeavor of Kierkegaard may be summed up under the heading of the question he pursued relentlessly: How can one become an individual? The individual was being swallowed up on the rational side by Hegel's vast logical "absolute Whole," on the economic side by the increasing objectification of the person, and on the moral and spiritual side by the soft and vapid religion of his day. Europe was ill, and was to become more so, not because knowledge or techniques were lacking but because of the want of passion, commitment. ""Away from Speculation, away from the System," he called, and "back to reality!" p.69
Rollo May
It's not as simple as that. Knowledge is necessary, too. An intuitive child couldn't accomplish anything without some knowledge. There will come a point in everyone's life, however, where only intuition can make the leap ahead, without ever knowing precisely how. One can never know why, but one must accept intuition as a fact.
Albert Einstein
First, we must consider what soul is. It is, then, that by which the animate differs from the inanimate. The difference lies in motion, sensation, imagination, intelligence. Soul therefore, when irrational, is the life of sense and imagination; when rational, it is the life which controls sense and imagination and uses reason. The irrational soul depends on the affections of the body; it feels desire and anger irrationally. The rational soul both, with the help of reason, despises the body, and, fighting against the irrational soul, produces either virtue or vice, according as it is victorious or defeated.
