"Great philosophical systems are never produced in a scientific vacuum but usually follow the formation and completion of a scientific world-perspective."

“As a result of scientific man's creativity there arises an ordered, illumined, determined world, imprinted with the stamp of creative intellect, of pure reason and clear cognition. From the midst of the order and lawfulness we hear a new song, the song of the creature to the Creator, the song of the cosmos to its Maker.”

“Not only the qualitative world bursts forth in song, but so does the quantitative.”

“Halakhic man, well furnished with rules, judgments, and fundamental principles, draws near the world with an a priori relation. His approach begins with an ideal creation and concludes with a real one. To whom may he be compared? To a mathematician who fashions an ideal world and then uses it for the purpose of establishing a relationship between it and the real world. ... The essence of the Halakhah, which was received from God, consists in creating an ideal world and cognizing the relationship between that ideal world and our concrete environment.”

“On the night of the exodus, the people met God, had a rendezvous with Him, and made His acquaintance for the first time. On Yom Kippur night, man gets very close to his Father in heaven, again meets Him, talks to Him, cries before and implores Him. The grandeur and singularity of these two nights lie in the God-man confrontation.”

“Perhaps these experiences of cognitive man are lacking in the emotional dynamic and turbulent passion of aesthetic man; perhaps these experiences are devoid of flashy and externally impressive bursts of ecstasy or stychic enthusiasm. However, they are possessed of a profound depth and a clear penetrating vision. They do not flourish and then wither away like experiences that are only based on a vague, obscure moment of psychic upheaval.”

“There is a distinct reluctance, almost an unwillingness, on the part of Torah to grant man the privilege to consume meat. Man as an animal-eater is looked at askance by the Torah. There are definitive vegetarian tendencies in the Bible.”
