“Even though its common knowledge these days, it never ceases to amaze me that all the richness of our mental life - all our feelings, our emotions, our thoughts, our ambitions, our love life, our religious sentiments and even what each of us regards us his own intimate private self - is simply the activity of these little specks of jelly in your head, in your brain. There is nothing else.”

“To exist in this vast universe for a speck of time is the great gift of life. Our tiny sliver of time is our gift of life. It is our only life. The universe will go on, indifferent to our brief existence, but while we are here we touch not just part of that vastness, but also the lives around us. Life is the gift each of us has been given. Each life is our own and no one else's. It is precious beyond all counting. It is the greatest value we can have. Cherish it for what it truly is..... Your life is yours alone. Rise up and live it.”

“Of all the inanimate objects, of all men's creations, books are the nearest to us for they contain our very thoughts, our ambitions, our indignations, our illusions, our fidelity to the truth, and our persistent leanings to error. But most of all they resemble us in their precious hold on life.”

“You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all... Our memory is our coherence, our reason, our feeling, even our action. Without it we are nothing.”

“Every day our life was full of thoughts of the horrible present, and even our own death.”

“A purely mental life may be destructive if it leads us to substitute thought for life and ideas for actions. The activity proper to man is purely mental because man is not just a disembodied mind. Our destiny is to live out what we think, because unless we live what we know, we do not even know it. It is only by making our knowledge part of ourselves, through action, that we enter into the reality that is signified by our concepts.”
