Our character is determined more by the absence of certain experiences than by the experiences we have undergone.
You cannot acquire experience by making experiments. You cannot create experience. You must undergo it.
The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science.
Since our inner experiences consist of reproductions and combinations of sensory impressions, the concept of a soul without a body seem to me to be empty and devoid of meaning.
Our moments of inspiration are not lost though we have no particular poem to show for them; for those experiences have left an indelible impression, and we are ever and anon reminded of them.
Our experience hitherto justifies us in trusting that nature is the realization of the simplest that is mathematically conceivable.
