To mix science up with philosophy is only to produce a philosophy that has lost all its ideal value and a science that has lost all its practical value. It is for my private physician to tell me whether this or that food will kill me. It is for my private philosopher to tell me whether I ought to be killed.
The sole function of education...[is] to open the way to thinking and knowing, and the school, as the outstanding organ for the people's education, must serve that end exclusively.
My whole working philosophy is that the only stable happiness for mankind is that it shall live married in blessed union to woman-kind - intimacy, physical and psychical between a man and his wife. I wish to add that my state of bliss is by no means perfect.
With a background in science I am extremely interested in the meeting ground of science, theology, and philosophy, especially the ethical questions at the border of science and theology.
Religious and philosophical beliefs are, indeed, as dangerous as fire, and nothing can take from them that beauty of danger. But there is only one way of really guarding ourselves against the excessive danger of them, and that is to be steeped in philosophy and soaked in religion.
Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him. It is for this reason chiefly that we have philosophy and religion.
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.
Gradually it has become clear to me what every great philosophy so far has been: namely, the personal confession of its author and a kind of involuntary and unconscious memoir.
